Evolution of isolated white dwarfs

Abstract

We consider evolution of isolated general relativistic uniformly-rotating white dwarfs which lose angular momentum via magnetic dipole braking. We show for selected constant mass sequences how the main parameters of white dwarfs such as the central density, mean radius and magneticfield change with time by fullling all stability criteria of the general relativistic uniformly-rotating congurations. Namely, we explicitly demonstrate that all isolated white dwarfs by angular momentum loss will be shrinking in order to reach stable equilibrium states.
