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(adsbygoogle = window.adsbygoogle || []).push({});

[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 ?
