What happens if you type "difference between type Ia supernova and nova" into your favourite search engine?

He might have meant in Celestia (idk really).
Otherwise, simply use a search engine.

Celestia does not incorporate stellar evolution or end-of-life scenarios for stars.

It would be pretty cool if you could set "stages" for a star and then parameters such as how quick the transition is and what textures and models to use for what stage.
Eg.
Code: Select all
Stage "Giant"
{
Beginning 2402634.6
ExpansionRate 17.4556 #km per year, or something like that. Negative value for collapse
TextureChange
{
Beginning 2402634.6
texture "red_giant.*"
ChangeRate 0.21 #percent of new texture shown per year
End 2421948
}
End 2422313
}
Stage "Collapse"
{
Beginning 2422313
ExpansionRate -2523174
ExpansionStopSize 14204 #stop expansion/collapse when star's radius in km is this value
TextureChange
{
Beginning 2422313
texture "white_dwarf.*"
ChangeRate 20
ChangeLength 5 #how long the texture change will occur in years
}
}

Celestia has features which can be used to produce something like that, but it could be a lot better.
You might take a look at Frank Gregorio's Edu package. I believe it includes a stellar evolution activity.
