Type Ia supernova and nova?

Type Ia supernova and nova...

is the same for me what is difference between a Type Ia supernova and nova?

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

Like this.

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.
