Right, the backstory is that there was a Terran civilization which collapsed long ago (in the far future for us) and the natives of B1 and A4 have had to bootstrap themselves back up from the stone age. The basic idea is to have a way to have first-contact situations, retro-style space colonization, and humanoid "aliens" in a hard-scifi setting.
B1, as you might notice above, is really, really dense. It has a very massive iron core, believed to be due to having had most of its mantle blown off in geologic deep time (like Mercury). I deliberately didn't put any planets inside its orbit in order to imply that it migrated out. When it was terraformed, there were quite a lot of volatiles to be sequestered, and so there are now veins of iron and nickel that was created by the terraforming nanites. In an old sideblog of mine (http://shaunwritesstuff.tumblr.com/post ... two-worlds) I went into a lot of detail about an earlier version of the idea, most of the details of which still hold. (The names for the planets, as you can probably guess from the fact that I haven't used them in this post, probably won't.)
I also deliberately gave the stars large eccentricities. A major theme of the story I want to write is about having to get from B1 to A4 while the stars are relatively close together because that won't happen for another...I don't know; there weren't any videos on how long the stars take to orbit one another. I also deliberately had the "forbidden zone" intrude so close in spite of Artifexian's instruction to explain why there's no planets outside of 20 AU from their primaries. (Earth continents added for reference.) Those numbered lists at the center of the second picture denote the number of days to each month of the local year; ".5"s denote where you put a leap day.
So my question is, am I doing this, just, even remotely right? I'd also like to know what the orbital period for the stars around each other is--and I'm sure there's things I haven't even thought of.
