Astrophysics (WHITE DWARFS)

Hey guys how do you find the mass and the radius of a white dwarf star knowing the density and the pressure of the star in the center?

Ask Jesus.

Damn right it is. Jesus is the answer to the Unified Theory problem.

I like elves better. Dwarves are not very hot.

hm... I don't know the answers, but here's some starting places.

if you know the pressure at the center, then you know how much the star stuff above it is pressing down on it.  that should give you the weight of the stuff pressing down on it. 

since you know the average density, you should be able to find an integral of density from the center to the ouside radius as a function of radius using the pressure and some information about gravity.

don't know exactly how to do this, or if I'm right, but it may be a place to start.
