Two Planetary Systems

February 18, 2022 Sharrukin Comments 0 Comment

Time for a quick taste of how the new Architect of Worlds version is turning out.

Long-time followers of this project will remember the two running examples in the draft: planetary systems named Arcadia and Beta Nine that are intended to demonstrate how the system works in practice. I’m in the process of re-working all of the examples, which should be the last step before I share the current draft with my patrons and my readers here.

Here are a couple of tables to suggest some of the results of the revised system.

Arcadia Planetary System
Orbital Radius	Planet Type	Planet Mass	Density	Radius	Surface Gravity
0.254 AU	Terrestrial Planet	0.26	0.75	4470 km	0.53 g
0.380 AU	Terrestrial Planet	1.75	1.09	7460 km	1.28 g
0.580 AU	Terrestrial Planet	1.34	1.10	6800 km	1.17 g
1.00 AU	Terrestrial Planet	0.22	0.74	4250 km	0.49 g
2.12 AU	Planetoid Belt	N/A	N/A	N/A	N/A
4.08 AU	Large Gas Giant	460	0.20	84100 km	2.64 g
8.12 AU	Medium Gas Giant	180	0.075	85300 km	1.00 g
12.0 AU	Small Gas Giant	52.0	0.14	45800 km	1.00 g
17.6 AU	Failed Core	2.80	1.13	8620 km	1.53 g

Not too many surprises here – this resembles the previous version’s Arcadia system fairly strongly. For some context, the primary star here is a singleton K2V, with about four-fifths the mass and one-third the luminosity of Sol. The third planet (at 0.58 AU) is the Earthlike candidate that I intend to use as an example for the last portion of the design sequence.

Beta Nine Planetary System
Orbital Radius	Planet Type	Planet Mass	Density	Radius	Surface Gravity
0.027 AU	Terrestrial Planet	1.22	1.09	6610 km	1.13 g
0.038 AU	Terrestrial Planet	0.94	1.01	6220 km	0.99 g
0.062 AU	Planetoid Belt	N/A	N/A	N/A	N/A
0.135 AU	Small Gas Giant	12.0	0.29	22000 km	1.00 g
0.390 AU	Failed Core	2.80	1.16	8540 km	1.56 g

The Beta Nine primary is an M4V red dwarf, with about 0.18 solar masses and less than 1% of Sol’s luminosity. It also has a brown-dwarf companion that cuts off planetary formation too far away from the primary. This planetary system is actually quite a bit different from the previous draft’s Beta Nine. The new model I’m using provides enough planetesimal mass for at least a small gas giant world, and it also allows for the possibility that some of that planetesimal mass “migrates” into the inner system to help form rocky worlds. So we end up with more planets this time, and the terrestrial worlds are considerably bigger.

One inspiration here is the TRAPPIST-1 planetary system. My old model didn’t have much trouble generating a planetary system like that for a small red dwarf, but it needed a pretty massive protoplanetary disk to do it. Under the new model, a red dwarf star doesn’t need an improbably big disk mass to have a chance at Earth-sized worlds. Given how many red dwarfs we’ve found with planets of significant size, I suspect the new model fits the facts better.

I’m hoping to have the new draft out as a free update for my patrons, and as an update to the version posted on this site, within a few days.

Planning for February 2022

February 2, 2022 Sharrukin Comments 0 Comment

Well, my day job is a little less demanding as January turns into February – my two big projects for calendar year 2021 are almost finished and I don’t have any big new projects for 2022. At least not yet. So I’m expecting to make good progress on a couple of creative projects this month. Here’s the main list:

Top Priority (“this is how I’ll judge whether the month has been successful”)
- Architect of Worlds: Rewrite sections of the Introduction and Design Sequence segment, based on new research, hopefully simplifying several steps of the sequence having to do with the placement of planets. I may also take this opportunity to update all the worked examples and make all the mathematical notation more consistent.
- Human Destiny: Finish the novelette “Remnants” for eventual collection and publication.
- Human Destiny: Finish writing an article for the Cepheus Journal about the game-book project.
Second Priority (“work on this as time permits”):
- Krava’s Legend: Write a few new chapters of The Sunlit Lands.
- Architect of Worlds: Start work on a section describing the structure of the galaxy and of interstellar space, and providing guidelines on how to make maps for interstellar settings.
- Human Destiny: Produce a high-level map of terraformed Mars.
- Human Destiny: Research and produce a timeline for the terraforming of Mars.
- Scorpius Reach: Write a few new chapters of Second Dawn.
Back Burner (“work on this only if everything else gets blocked”):
- Architect of Worlds: Start work on a section of special cases and additional worldbuilding material that doesn’t fit into the design sequence.
- Krava’s Legend: Write the second short story for the “reader magnet” collection.
- Scorpius Reach: Start work on a third edition of the Game of Empire rules for Traveller (or Cepheus Engine)

The work on Architect of Worlds is probably the top priority this month. The end result there will probably be a version 0.8 draft of the Introduction and World Design Sequence. That new document will be a free update for my patrons.

I’m also considering releasing the new partial for free on this blog site, in an attempt to generate some new interest for the project. There have been a lot of changes and improvements since the version that’s currently available to the public. My patrons will continue to get any further updates to that document as free rewards, until there’s another major overhaul or the book as a whole is about ready for layout and release.

Meanwhile, I should be able to complete the novelette “Remnants” this month, and if that ends up being long enough, I’ll likely make it the charged release for February.

Status Report (30 January 2022)

Well, the honey and the biscuits are not quite coming out even.

I’m making decent progress on “Remnants,” a new Human Destiny novelette. However, that’s going more slowly than I had expected; I’m discovering that writing a murder mystery is a bit more challenging than my usual genre. I’ve also settled on an indie novel to review before the end of the month, and I’m plowing through that text at a rapid pace. Unfortunately, I don’t think I have enough free hours left before the end of the month to get both tasks finished.

Doing at least one book review a month has to take precedence, so as a result, there will be no charged release for my patrons for January 2022. I’ll most likely be able to finish “Remnants” in the first week or so of February, and that will probably be the next charged release. I haven’t settled on the next major project to get attention, but I suspect I may be looking hard at a major round of revisions to the Architect of Worlds design sequence, based on the new research I mentioned in this post from last week.

More news early in February.

New Models for Planetary Formation

January 24, 2022 Sharrukin Comments 5 comments

The science of planetary formation has been advancing in leaps and bounds for the last decade or two, driven by the discovery of thousands of exoplanets and fine-detail imaging of other planetary systems. This has been giving us a lot of insight into not only the history of our own Solar System, but also the general case of planetary formation elsewhere.

With my Architect of Worlds project, I’ve been trying to keep abreast of the current science while designing a world-building system for use in game design and literary work. The current state of the system is pretty good, I think, but it’s a bit complicated. I’ve built a model that tracks the formation of a system’s primary gas giant (if any), follows that planet as it migrates inward (and possibly outward), and uses the results of that evolution to determine the mass and placement of the rest of the planets. Lots of moving parts there, and a few of the steps are kind of unwieldy.

Now there’s some recent research suggesting that I might be able to simplify the model and still get good results. The pertinent paper is “Planetesimal rings as the cause of the Solar System’s planetary architecture,” by Andre Izidoro et al., released in December 2021. Here’s a layman’s article from Rice University: “Earth isn’t ‘super’ because the sun had rings before planets,” published on 4 January.

The idea is that it wasn’t specifically the migrations of Jupiter that brought about the architecture we see of the inner Solar System. Instead, the protoplanetary disk probably had several “pressure bumps,” places where infalling particles released gases due to the increasing temperature close to the embryonic Sun. These pressure bumps tended to accumulate dust particles, and created an environment where planetesimals could form and coalesce, without continuing to spiral into the Sun. The authors of the paper predict the presence of three such “pressure bumps,” which ended up giving rise to the rocky inner planets, the gas giants, and the Kuiper Belt objects respectively.

The idea makes a lot of sense, especially since we’ve started to get fine-detail images of young stars and their protoplanetary disks, and we sometimes see exactly the system of “rings” that the model would predict. Take the image that leads the Rice University article, which I’ve included above.

Scientifically, speaking, the neat thing about this new model is that it explains several things that previous models (which assumed a more uniform disk and relied on Jupiter-migrations to make things work out) had trouble with – especially the specific isotopic composition of inner-system as opposed to outer-system material. The new model also doesn’t have any trouble producing a small Mercury or Mars, or a planetoid belt (with mixed composition) between Mars and Jupiter.

From my perspective, it may mean that I can simplify the model on which Architect of Worlds is built, making the whole thing much easier for people to use. I’m going to be reading the literature on this, and thinking about the implications.

Planning for January 2022

January 8, 2022 Sharrukin Comments 0 Comment

Things have been a little hectic here at the Palace lately. The period since Christmas has, ironically, been one of the busiest I’ve had at my day job in some time, with three major projects all coming to a head at the same time and demanding a lot of my attention. On top of that, throw the disruption of the worst surge since the pandemic started and our usual pattern of getting heavy snow in January, and it’s kind of been chaos. Not conducive to getting creative work done.

Still, I have a calm weekend at the moment, and it’s a good time to outline work for the rest of this month.

Top Priority (“this is how I’ll judge whether the month has been successful”)
- Human Destiny: Finish a draft of the character design rules and release the first partial draft of the Human Destiny setting bible as a Cepheus Prime sourcebook.
- Human Destiny: Finish a new novelette for eventual collection and publication.
- Human Destiny: Produce a high-level map of terraformed Mars.
- Human Destiny: Research and produce a timeline for the terraforming of Mars.
Second Priority (“work on this as time permits”):
- Krava’s Legend: Write a few new chapters of The Sunlit Lands.
- Architect of Worlds: Start work on a section describing the structure of the galaxy and of interstellar space, and providing guidelines on how to make maps for interstellar settings.
- Architect of Worlds: Start work on a section of special cases and additional worldbuilding material that doesn’t fit into the design sequence.
- Scorpius Reach: Write a few new chapters of Second Dawn.
Back Burner (“work on this only if everything else gets blocked”):
- Architect of Worlds: Return to improvement and polishing of the Introduction and Design Sequence document, leading to a new minor-version release. This work may involve updating all of the worked examples, and making mathematical notation more consistent.
- Krava’s Legend: Write the second short story for the “reader magnet” collection.
- Scorpius Reach: Start work on a third edition of the Game of Empire rules for Traveller (or Cepheus Engine)

I’m clearly focusing on the Human Destiny universe some more this month. I’ve actually worked out most of the Martian material, although it’s all scattered notes at the moment, and producing the map is proving a little more challenging than I thought. I’m making good progress on the Cepheus Engine hack for the sourcebook. Meanwhile, I’ve come across one of my older partial stories – possibly the first piece of fiction I ever wrote in the setting that eventually became Human Destiny – and it seems likely that I’ll be able to finish that fairly quickly. So that’s where the low-hanging fruit are at the moment.

For my patrons, the most likely releases this month will be the next partial rough draft of the sourcebook (free release) and the new story (charged release, if it’s long enough). As always, I’ll update as the month progresses and it’s clearer how things are going to go.

2021 in Review

January 1, 2022 Sharrukin Comments 0 Comment

In some ways, 2021 was a pretty good year at the Palace. The blog has been growing steadily every year since I resumed it in 2018, and 2021 was no exception. We got several thousand distinct views, which isn’t bad for a non-themed, meandering blog by a part-time creative. On the Patreon side of things, I’ve reached almost two dozen active patrons. I’m not sure yet, but I think income from my original work is approaching the level that I make on the long tail from my tabletop industry period years back. Not a bad milestone, even if it’s still orders of magnitude short of “quit the day job” money.

This was the first full year after I started cross-posting to social media. It was also the first full year since I started posting one or two reviews per month of self-published or indie fiction. Those no doubt helped.

As usual, the main factors holding me back are the part-time nature of my work, and the fact that I likely have too many distinct projects under way. Those items make it hard for me to hit major milestones. For example, it’s been over a year since my debut novel, The Curse of Steel, was released – yet the sequel, The Sunlit Lands, is still not nearly complete in first draft. I started a space-opera novel, Second Dawn, for Kindle Vella but that project has been stalled too. My main non-fiction project, Architect of Worlds, made significant progress but still isn’t close to being finished.

My creative style seems to work for me – I don’t get completely blocked very often, and I usually make progress on something every month. I worry that it demands patience from my readers, though.

Anyway. I usually take this opportunity to look back on the top-ten new posts from the previous year. This year looks kind of different on that score. My book reviews are clearly driving some traffic, and when I can connect my work to the popular RPG Traveller, that seems to bring a lot of clicks. Something to keep in mind.

Overall, I think my goals for the coming year are going to involve two meta-objectives: to make progress on all of my outstanding projects, and at the same time to finish one of the book-length items. The best candidates for the latter are Architect of Worlds and The Sunlit Lands. Still, we’ll have to see how things go.

Planning for December 2021

December 8, 2021 Sharrukin Comments 1 comment

I think I may have diagnosed the long-period creative slump I was in for most of the fall.

About mid-November, I summarily ejected an unproductive activity that had been taking up some time every day since the height of the pandemic: playing one or another MMO online. Back when I was on extended medical leave, working from home if at all, spending an hour or two a day gaming wasn’t an issue. Once I was back in the office full-time, and especially given that my workload there has stepped up a bit since the summer, it was crowding out time and energy that could have been spent on creative work. One day I decided to shut the most recent game down cold turkey – gave away all my in-game assets, closed out my account – and almost the very next day I found myself getting unblocked. We often don’t realize what’s damming the creative flow until we find the problem and patch it.

So November was yet another month with no big milestones and no major releases, but December is already looking like a big improvement. I have a Human Destiny novelette that’s well on its way to completion in first draft, and I’m making good progress on a new section of the setting bible for that universe.

So, without further ado, here’s the outline for the month of December.

Top Priority (“this is how I’ll judge whether the month has been successful”)
- Human Destiny: Finish the new novelette “Roanoke” for eventual collection and publication.
- Human Destiny: Research and produce a timeline for the terraforming of Mars in this universe.
- Human Destiny: Produce a high-level map of terraformed Mars for the Cortex Prime sourcebook and setting bible.
- Human Destiny: Write a few thousand more words of the Cortex Prime sourcebook and setting bible.
Second Priority (“work on this as time permits”):
- Krava’s Legend: Write a few new chapters of The Sunlit Lands.
- Architect of Worlds: Start work on a section describing the structure of the galaxy and of interstellar space, and providing guidelines on how to make maps for interstellar settings.
- Architect of Worlds: Start work on a section of special cases and additional worldbuilding material that doesn’t fit into the design sequence.
- Scorpius Reach: Write a few new chapters of Second Dawn.
Back Burner (“work on this only if everything else gets blocked”):
- Architect of Worlds: Return to improvement and polishing of the Introduction and Design Sequence document, leading to a new minor-version release. This work may involve updating all of the worked examples, and making mathematical notation more consistent.
- Krava’s Legend: Write the second short story for the “reader magnet” collection.
- Scorpius Reach: Start work on a third edition of the Game of Empire rules for Traveller.

Clearly the Human Destiny material is going to get the lion’s share of my attention this month. I should be able to finish “Roanoke” within another week or so, and that’s likely to be at least 10,000 words of new material all by itself. The setting bible is going to get a big chunk of new material as well.

Most likely, my patrons are going to get a final draft of “Roanoke” as a charged release this month, with the understanding that there’s also going to be a free update to the Human Destiny setting bible that incorporates a bunch of new material. We’ll see what else might make progress as well over the next few weeks.

Planning for November 2021

November 1, 2021 Sharrukin Comments 0 Comment

I seem to be in a long-term slump when it comes to creative effort. For a couple of months now, progress has been slow and rather scattered on all of my outstanding projects – I’ve made some progress in several areas, but no one item has moved forward enough to generate a significant milestone. Neither have I generated any new content in a big enough block to justify issuing a charged release for my patrons. About the only real milestone I hit was to publish this month’s book review.

Hard to say what’s behind this. It’s probably some mix of needing to spend most of my creative spoons on my day job, getting distracted by day-to-day concerns, and some mild dysphoria that’s making it hard to focus. The upshot is that October, like September, was something of a wash.

Yet hope springs eternal, and part of my creative discipline involves at least taking stock and laying out a plan at the beginning of each month. So here’s the plan for November.

Not much change from last month, except that I think I’m going to move a new Human Destiny short story up on the priority list – I have a concept that seems to be pushing its way to the front of my mind. Also with respect to Human Destiny, I’ve been doing a lot of research and prep work to develop a timeline for the terraforming of Mars – I think several stories in that setting will eventually be tied to that piece of it. I might push that subproject forward this month.

Top Priority (“this is how I’ll judge whether the month has been successful”)
- Krava’s Legend: Write a few new chapters of The Sunlit Lands.
- Human Destiny: Research and produce a timeline for the terraforming of Mars in this universe.
- Human Destiny: Write a new short story for eventual collection and publication.
Second Priority (“work on this as time permits”):
- Architect of Worlds: Start work on a section describing the structure of the galaxy and of interstellar space, and providing guidelines on how to make maps for interstellar settings.
- Architect of Worlds: Start work on a section of special cases and additional worldbuilding material that doesn’t fit into the design sequence.
- Human Destiny: Write a few thousand more words of the Cortex Prime sourcebook and setting bible.
- Scorpius Reach: Write a few new chapters of Second Dawn.
Back Burner (“work on this only if everything else gets blocked”):
- Architect of Worlds: Return to improvement and polishing of the Introduction and Design Sequence document, leading to a new minor-version release. This work may involve updating all of the worked examples, and making mathematical notation more consistent.
- Krava’s Legend: Write the second short story for the “reader magnet” collection.
- Scorpius Reach: Start work on a third edition of the Game of Empire rules for Traveller.

If I can produce enough new prose between The Sunlit Lands and a Human Destiny story, that will likely be a charged release for my patrons this month. If some of the Second Priority material makes progress, I’ll likely post that to my blog and share it with my patrons for free as well. I also have a couple of good candidates for book reviews for the month of November.

Planning for October 2021

October 2, 2021 Sharrukin Comments 0 Comment

Well, September didn’t go according to plan on any level, but I did manage to get a few creative tasks done:

I produced a new minor update for the main portion of Architect of Worlds, and shared that with my patrons as a free update.
I finished revising “In the House of War” and published it through Amazon and a number of other outlets. The workflow for that involved the Draft2Digital service, which worked out rather nicely – I think that will be the default for future fiction releases.
I published a book review.

Reviewing all of the open projects, I think I’m most concerned to get some new fiction written. Second Dawn has been hanging fire at six chapters since the Kindle Vella service went live. Even worse, it’s been over a year now since The Curse of Steel was released, and I’m no closer to having the sequel finished than I was in the spring. Time to start cranking out some chapters for one or both of those!

So here’s the plan for the month of October:

Top Priority (“this is how I’ll judge whether the month has been successful”):
- Krava’s Legend: Write a few new chapters of The Sunlit Lands.
- Scorpius Reach: Write a few new chapters of Second Dawn.
Second Priority (“work on this as time permits”):
- Architect of Worlds: Start work on a section describing the structure of the galaxy and of interstellar space, and providing guidelines on how to make maps for interstellar settings.
- Architect of Worlds: Start work on a section of special cases and additional worldbuilding material that doesn’t fit into the design sequence.
- Human Destiny: Write a few thousand more words of the Cortex Prime sourcebook and setting bible.
- Human Destiny: Write a new short story for eventual collection and publication.
- Krava’s Legend: More research toward improvements to my release-and-marketing workflow.
Back Burner (“work on this only if everything else gets blocked”):
- Architect of Worlds: Return to improvement and polishing of the Introduction and Design Sequence document, leading to a new minor-version release. This work may involve updating all of the worked examples, and making mathematical notation more consistent.
- Krava’s Legend: Write the second short story for the “reader magnet” collection.
- Scorpius Reach: Start work on a third edition of the Game of Empire rules for Traveller.

Ideally, I’ll produce at least six chapters each of The Sunlit Lands and Second Dawn, that can be this month’s charged release for my patrons, and I’ll be able to polish and publish the Second Dawn chapters next month. If any of the Architect of Worlds documents or the Human Destiny setting bible make enough progress, those will turn into free updates. As always, I’ll want to complete one or two book reviews for self-published or indie fiction this month.

Status Report (19 September 2021)

September 19, 2021 Sharrukin Comments 0 Comment

Very little about this month has been going according to plan, least of all finding the time to get some solid creative work in. Still, the shape of what’s left of September is starting to become clear. So here’s the (more informal than usual) task list for the next couple of weeks:

Architect of Worlds: Produce a new minor-version release of the main body of the book, the Introduction and design sequence. I’ve already made a number of minor changes. I have in mind a extensive modification that should simplify and clarify a big section of the current design sequence. This should end up with a free update for my patrons by the end of September – a version 0.7 alpha release for that document.
Human Destiny: I plan to release “In the House of War” as a new self-published novella by the end of this month. That’s dependent on me being able to come up with a decent cover image and get the ebook formatted on time, of course, but I think that’s within reach. My patrons at the $2 level and above will be getting a free copy of the PDF, and hopefully a Kindle-compatible ebook as well.
Book Reviews: I still need to complete a self-published book for review for September. I have a couple of promising candidates here.

The critical fact is that there will be no charged release for my patrons for September. Hopefully October will be a bit more conducive to new work.

A side note: I’ve adjusted my social-media strategy a bit. I no longer maintain a “business page” on Facebook as a place for posts from this blog to appear. Instead, I’ll be simply posting links to new blog posts from my personal FB page. An extra step, but to be honest, the business page wasn’t getting picked up by very many people. So if you follow me on Facebook you’ll probably have a better chance of seeing these posts.
