How to prevent stars from becoming binaries?

I made a Wolf-Rayet star and now there's a much brighter O star orbiting with it. I tried making a barycenter but now the catalog entry is duplicated. Any suggestions?

arbelrocks,
You must give the 'StarBarycenter' a different name.

For example:

Code

StarBarycenter "MyStar System"
{
    RA      xx xx xx
    Dec     xx xx xx
    Dist    xxxx
}

Code

Star "MyStar"
{
    ParentBody  "MyStar System"

    ....
    ....

}

And you need two scripts!

The script for the 'StarBarycenter' belongs in the folder 'addons\catalogs\stars' and the script for the 'Star' belongs in the folder 'addons\catalogs\planets'

Don't forget to look here.

Yes, but what should I call it? I am making an entry for a star that exists in real life.

Okay, here's an example.

The 'StarBarycenter':

Code

// Name: R136a2_BC.sc
// https://en.wikipedia.org/wiki/R136a2

// Put this file in 'addons\catalogs\stars'

//------------------------------------------------------------------------------
StarBarycenter    "R136a2 barycenter"
{
    RA          05 38 42.40
    Dec         -69 06 02.88
    Dist        50000
}

//------------------------------------------------------------------------------

The 'Star':

Code

// Name: R136a2.sc
// https://en.wikipedia.org/wiki/R136a2

// Put this file in 'addons\catalogs\planets'
//------------------------------------------------------------------------------

Star    "R136a2/MH 511/RMC 136a2/HSH95 5/BAT99 109/CHH92 2"
{
    ParentBody "R136a2 barycenter"
    Class       "WN5"       //"WN5h"

    MassSol     195
    RadSol      23.4

    AppMagn     12.34
    Luminosity  4266000

    Temperature 53000

    Age         0.0003
}

//------------------------------------------------------------------------------
