Sigma Binary stars with a planet at the barycenter

[Superfluous J]

This was split off from the comments on another thread (thanks Gargamel for doing that for me) so may be a bit disjointed, but I wanted a thread where I could discuss this as its own topic.

I saw you on the Kopernicus Discord, i wonder what kind of Planet Pack you'll make

I have a very specific idea that I don't think will even work, but I want to actually try it before I ask any questions. The big problem with that right now is that I worked 2 unexpected extra days this week so have had very close to 0 free time. Also, Factorio

But the idea is planet "Barry," at the barycenter of 2 (KSP-sized) red dwarfs, orbiting each other at some distance. Each dwarf has a small planet orbiting it and then the system itself has a couple inner planets and a large outer one. I may even reuse all of KSP's planets. Except Kerbin, because Barry will be 90% hellscape and 10% "equatorial" belt, where the two stars are on the horizon and the surface isn't so hot. The planet will be "tidally locked" to the two stars, so rotate once each of their years.

I don't care that it wouldn't work in reality, so lay off that But what I'm not sure of is if it'll work in Sigma Binary.

K, beware of Gregrox, he might be mad at Unrealistic stuff...

it should work fine with SB, this is how you should set up the system

 

1- put the primary star in the final orbit for your system (the orbit that the barycenter eventually will have)

2- put the secondary star in orbit around the primary star, the semiMajorAxis of the secondary star should be the final distance you want between the two stars

3- add the "SigmaBinary{}" node to the secondary star
(make sure to add the parameter  name = xxxxxxx because otherwise SB won't work)

4- test that the system works

5- add Barry in orbit around the primary star, you need to find an orbit that will keep the planet always in the correct place
(if you have issues with this step ping me on discord I should be able to help)

6- check that Barry is in the correct Sphere Of Influence, if not you might need to put barry in orbit around the secondary star

@Sigma88

He wants to put a Binary Red Dwarf, and put "Barry" in the middle of them, where The Red Dwarves' Gravities are Nullified...

yes that's what I understand as well,

 

as long as the two stars are added as an extra system this is possible with SB, if they are supposed to replace the stock sun as the new center of the ksp universe, I am not 100% sure it would be possible to do with SB

That was the intent, yes, to replace the stock sun with the binary. However there's no reason I can't break that personal rule to get it to work in the game rules.

I hope to play with it tonight and will ask any questions I have.

@5thHorseman, Thread is split off, you are OP, as requested, if you'd prefer it moved to Add-on discussion, drop us a line.  @GRS, your question that started the thread was left behind so VHM could be OP in this one.   Because that is what started the Off topic conversation (good call requesting the split btw), I have removed that question from the tail end of Kerpollo thread, although VHM did quote the meat of it here.   Questions or concerns with this split can be directed to @adsii1970 as he has no idea what I just did.   And moved to Add-on Discussion.
