Help on stars again please

[Mr Noob]

Hi again

I remember the last time I asked about creating stars. That was when I was in my early days of system making. Now I would like to know something else...

The question... How do I put a star in orbit around another star ?

I have some data on a system I have just begun creating. Here it is

Code: Select all

118323 "Tr'il:Zeta ZSC" {
   RA  143.91333333
   Dec  11.25000000
   Distance  13702.8001
   SpectralType "GIV"
   AppMag 18.00
}

I would like a star put in orbit around Tr'il at a distance of 32 AU.

Thanks for any help... Mr Noob

P.S I am creating systems again. My computer is 100% healthy and fixed

Hi Mr. Noob,

just a short question first. Are you aware of my STC-Guide at the Motherlode?
There are the explanations for the STC commands and also some quick examples of star systems.

Second question is: Do you really want to create a star that is actually orbiting an other star or do you want both stars to orbit around a commen center of gravity, called barycenter?

To just orbit a second star around the first one, you could do something like this:

Code: Select all

118323 "Tr'il:Zeta ZSC" {
   RA  143.91333333
   Dec  11.25000000
   Distance  13702.8001
   SpectralType "GIV"
   AppMag 18.00
}

"Star 2"
{
   OrbitBarycenter "Zeta ZSC"
   SpectralType "WN1II"
   AbsMag -6.4

        EllipticalOrbit
   {
                Period         10.31853526
                SemiMajorAxis   32
                Eccentricity    0.186
                Inclination     11.56742
                AscendingNode   25.34563
                MeanAnomaly      167.467
        }
}

That's now just a real quick and dirty copy paste from one of my double stars. But I think it shows you the direction.

Hope this helps.
