In the simplistic treatement of white dwarfs we covered in my thermo class, we obtained an expression for the total energy of the star, namely
[tex]E=\frac{A}{R^2}-\frac{B}{R}[/tex]
where A and B are constants. Then, we said that the actual radius of the dwarf is the radius that minimizes the energy.
On what principles is this reasoning based ?
