| I thought it'd be cool to have a catalog of known (currently available) data of extragalactic stars. I know the engine has trouble rendering stars at that distance, but considering the amount of information I've got to work with and the size of each star's data, it should be easily upgraded when the bug is fixed.
I found most were in the Large Magellanic Cloud, which is good for accuracy even though it still does the jittery thing, but I noticed something else. Their solar luminosities are in the hundreds of thousands to millions! I checked the other stars and they seemed to be right around 1, I couldn't find any extremes(at least in the scripts). Is it bad to put stars in SE with these massive values though? I set them to 50, but then I can't see them like the stars in our quadrant of the galaxy and the one I put in Andromeda is huge in comparison to the stars around it.
I also tweaked around the dec and right ascension and I thought it should have made a huge difference at that distance, but the one I placed in Andromeda barely budged.
Another thing I noticed is that these stars are class LMV and the best I can do in SE is set them to B0II where B is the only part near accurate in something called the "quietess" state.

...why would it be bad to put in a star with its real luminosity? All the stars in the LMC in the SE catalog are extremely bright stars, which is why they're included in the first place.

| I'm having an issue with my star. I'm trying to make an orange dwarf star, but ingame the info says it's a blue hypergiant and the star shows up as a black glitchy thing.
Here's the star code:
Code StarBarycenter "Garen"
{
RA 19 0 0 // Right ascention
Dec -5 0 0 // Declination
Dist 15.0 // Distanse from our Sun
Class "K5V" // Spectral class
Lum 0.153 // Luminosity, or
//AbsMagn 5.31 // absolute magnitude, or
//AppMagn 10.31 // visual magnitude
}
And the "planet" code:
Code Star "Garen"
{
ParentBody "Garen"
Class "K0 V"
AppMagn 4.785
Radius 0.53

| The biggest problem is that you have the two objects using the same name. You can't do that. Call the barycenter "Garen system" or something. Also, a few other things:
Why are you using a different star class in each script? And you're missing the space between K5 and V in the star script. And Why did you use Lum at the top, and AppMagn at the bottom? Also, radius should be expressed in kilometers, not Solar radii.

So I went and changed some things like you asked, I'm still getting the same errors.

EDIT: I figured it out. It turns out I had a second Garen barycenter in Stars.sc. Though I still have problems. Now the star doesn't show up at all.
EDIT2: I'm an idiot. I forgot to add them to the universe.cfg. Thanks for all your help. It works now!

SE allow to use or not use a space in the star class string.

| I have trouble adding a binary star. I don't know what the problems are, but it would be really helpful if somebody could figure it out. Below are the parameters.
Barycenter located in: catalogs/stars/Stars.sc
Code StarBarycenter "Boliverius Alvera Sagittarii"
{
RA 266.41683333
Dec -29.00780556
Dist 459.902087919
NoPlanets true
}
Stars located in: catalogs/planets/Stars.sc
Code Star "Boliverius Alvera Sagittarii A"
{
ParentBody "Boliverius Alvera Sagittarii"
AppMagn 17.0
Class "G V"
NoPlanets true // disable generation of procedural planetary system
Orbit
{
Type "Static"
Period 0.000001 // Orbital period in years
SemiMajorAxis 0.0 // Semimajor axis in astronomical units
}
}
Star "Boliverius Alvera Sagittarii B"
{
ParentBody "Boliverius Alvera Sagittarii A"
AppMagn 17.5
Class "G V"
NoPlanets true // disable generation of procedural planetary system
Orbit
{
Type "Static"
Period 79.914 // Orbital period in years
SemiMajorAxis 6300.0 // Semimajor axis in astronomical units
}
}
I am not gonna replace some stars. I am adding new stars. But the problem is that the binary star a.k.a Boliverius Alvera Sagittarii B is located inside the main-star Boliverius Alvera Sagittarii A. I want the binary star to be located 6300 AU from the main-star.

| Change the orbitd. They are in the static mode, so the stars are placed in the barycenter. Look at Toliman's code for an example.

| I planning to add some stars to the Andromeda Galaxy. I am not familiar of how i do that. Do i just add the Declination and the Right ascension and the distance to place a star there?

Yes. That is the only way to place a star.

| gift, could you please post the codes for your star here? Then we could help (from your .sc file it is located in)
I will be inactive on this forum for the time being. Might come back eventually
