Any information on the white dwarf mass-radius relation would help alot...URLs are helpful although direct info is perferred. Thanks

By mass-radius relation, I suppose you are talking about density. A white dwarf has a density about a million times greater than the sun's average density. About a ton per cubic centimeter.

A white dwarf is a stellar remnant left over from a super-nova explosion.
A white dwarf is a 2 to 3 solar mass body about 100 km in diameter,it is the last stage before a neutron star.

Not a technical expert, but when the sun becomes a white dwarf it will have approximately its current mass (or a bit less) in a volume about the size of Earth.

As a good approximation,
R/R๏ = −0.010421 (M/M๏) + 0.018821
Provided that
~0.4 < M/M๏ < ~1.2
Below 0.4 solar masses and above 1.2 solar masses, you can't use the linear fit because the second derivative of radius with mass becomes too large.
