It has been a long time since I have done anything with Celestia. Life has a habit of interrupting fun. Anyway, I am confused about the generation of planets in a multiple star system in an ssc, specifically in the Alf Cen B case.
When an extrasolar planet is added, which star naming designation do you have to use HIP, HD, etc. after the planet?
I always thought you could use any of the names listed.
In the ssc file you have "planet name" "star designation"
I notice that Grant uses a Draper number in the ssc, but in the starnames.dat and nearstars.stc the Hipparchos designation is used. Where is the HD number defined for Alf Cen B?
"b" "HD 128621" # Alf Cen B
I am trying to create a temporary planet in orbit around a 40 Eri A. 40 Eri A is orbiting around barycenter which has the HD and HIP designation (HD 26965, HIP 19849). 40 Eri A should have those designations, not the barycenter I think. 40 Eri B has yet another HD designation. I've created the planet fine around the barycenter, but that's not what I am trying to do. I was showing one of my students how a habitable zone could exist in a more compact trinary system than the Alpha Cen B system. He asked me what it would look like. So far, no go...
