Re: [Space] Multiple/Lots of Stars in one system
Okay then!
Your next step is to generate orbital separations, and to get a stable (and therefore plausible) system you want
I would suggest that rather than rolling, you just decide to make 1-4 a distant orbit, make a-2 and c-5 wide or wide and moderate, and then make b-e one step closer than a-2 and f-g one step closer than c-5. That done:

Re: [Space] Multiple/Lots of Stars in one system
According to what Brett was saying, the closest distance between a and b (min a<->b) must be greater than 3x max b<->e. Min a<->c must be at least 3x greater than max c<->f. Min c<->f must be greater than max f<->g. Basically, that's why the system doesn't actually allow you to generate distant sub-companions.

I'm also thinking I should generate the stats for star 6 and see if it has any companions (I think I've got enough stuff at this point to simply fiat rule NO) |

Re: [Space] Multiple/Lots of Stars in one system
Stars of 2 solar massses probably die too young to have Eartk-like planets.

Re: [Space] Multiple/Lots of Stars in one system
Yeah, their life-time on the main sequence is only about 1.3 billion years, and it took Earth about 2.2 billion years to oxidise its reducing environment and start accumulating excess oxygen.
Maybe the whole thing with biogenesis, the evolution of photosynthesis, and the production of enough oxygen to transform an Ocean World into a Garden World might go a bit quicker under some circumstances. Maybe if the visible illumination were higher, as on a planet in a relatively close orbit around a star that produced comparatively more visible light and less infra-red…. But when I crunch the numbers on that it comes out touch-and-go at best for anything hotter than about A7. Perhaps it might get lucky on rapid evolution….

Re: [Space] Multiple/Lots of Stars in one system
OK, I've changed things around and had LO Clac according to the following: If a star has a companion and orbits a star itself the first stars minimum separation from it's primary is 3 times the distance that it's companion companion minimum separation is from it, then calculate average and maximum separation based on that and eccentricity.
I may still adjust the numbers, because the maximum distance between a and e can reach 480 AU and the minimum distance between a and g can fall to 450 AU, so every few million years that part of space can get interesting and there's a small chance those stars (Or should that be Suns?) may hit each other, so something may need to change there. On the other hand the ratio between the minimum separations from a for b and c are 2.25 and I think that could be important |
