I really want to contribute here, but even after reading this entire thread and the "making a star" tutorial, I STILL don't understand how the RemoveStar command works. Can someone please explain?

This is for removing stars from the default binary-format catalog (stars120k.dat) so you can replace them with custom data.

In your star catalog, just type "RemoveStar" and then put the name of the star you wish to remove (e.g. "HIP 14810").

Code
RemoveStar "HIP 14810"

Then make your replacement for that star system.

I've just finished remaking the Polaris system. I've used all the data I could find about the stars of the system, from sources like Wikipedia and ArXiv.

NOTE: Polaris A and B are implemented as seperate systems altogether due to the large distance between them and the fact that there is virtually nothing known about B's orbit.

Code

RemoveStar    "Polaris"

StarBarycenter    "Polaris A"
{
   RA  02 31 49.09
   Dec    +89 15 50.8
   Dist    133
}

StarBarycenter    "Polaris B"
{
   RA  02 30 41.63
   Dec    +89 15 38.1
   Dist    132.98
}


Code

Star "Polaris AA"
{
   ParentBody    "Polaris A"
   Class          "F7Ib"
      Luminosity  2500
      Mass      4.5
      Radius    32016000
      Age           0.07
      RotationPeriod   2856   
   Orbit
   {
    Type "Static"
   }
}

Star "Polaris AB"
{
   ParentBody    "Polaris A"
   Class     "F6V"
   Luminosity    3
   Mass     1.26
   Radius  723840
   Age   0.07
   Orbit
   {
    Period    29.59
    SemiMajorAxis    18.8
          Eccentricity    0.608
          Inclination    128
          AscendingNode    0.0
          ArgOfPericenter  303
          MeanAnomaly    0.0   
   }
}

Star "Polaris B star"
{
   ParentBody  "Polaris B"
   Class  "F3V"
   Luminosity    3.9
   Mass     1.39
   Age   0.07
   RotationPeriod    15.23
   Orbit
   {
    Type "Static"
   }
}




EDIT: Just noticed an oversight. I've put Polaris AA's orbit as static, though it should be elliptical. I'll fix this later.

Okay, since I previously mentioned having modified the default DEL Tri star in SE to be a binary, I figured I'd upload it to this thread, sans my fictitious worlds. Admittedly, this star is a huge thorn in my side to research, as the info on this star varies hugely from website to website, not to mention the info seems rather scarce to begin with, since this star seems to be given such a low priority.

Any suggestions for improvements would be appreciated, as I stuck with the data I normally use for this star. smile

Thanks, I added this star to the binary stars catalog. By the way, you don't need to describe atmosphere - SE generate it automatically.

Earlier this year, I went on a worldbuilding spree, and managed to turn a few existing known stars into binaries. Unfortunately a lot of them are speculative in nature, but I did my best to at least check out the Simbad databases and the Naval Observatory's Sixth Catalog of Orbits of Visual Binary Stars (which is currently down at the time of this post) to cross reference the available data that I could find, in addition to the Wikipedia pages. The stars involved are:

Achernar (Alf Eri)

Antares (Alf Sco)

Beta Centauri

Capella (Alf Aur)

Rigel (Bet Ori)

Spica (Alf Vir)

I'll attach them as a zip, separated by the usual "planets" and "stars" folders. smile

I forgot this thread after doing a catalog of binary-multiple stars here. Like Plutonian I used 6th Catalog of Visual Binaries, SIMBAD, some astronomical articles and the wikipedia. Surprisingly spanish wiki seems to have more binaries, as long they are also using some variable star catalogs and describing a lot of eclipsing binaries. But anyway I'm just an astronomy enthusiast and I could do some things wrong.

Whatever, take a look in my catalog and be free to use as much data or stars as you want, if that helps you in anyway. I'm always happy to contribute in anyway.
