Does anyone know the mathematical form of Type Ia supernovae light curves? I am trying to analyze supernovae data. I need to fit a function to the magnitude vs time data. So I require the mathematical form for magnitude as a function of time. If anyone has any idea about that, or can suggest a way to bypass this problem PLEASE let me know.

There are any number of curve fitting algorithms that could be applied. Here is one that may be useful  http://supernovae.in2p3.fr/~guy/salt/

Type Ia Supernovae Light Curves
Apparently, it only runs under Linux and Mac OS. It also appears to require compilation in fortran. Here are some other sources that may be more user friendly  http://www.mpagarching.mpg.de/lectu...Niedermann.pdf,

These kinds of things usually run well under Cygwin in windows.
