White dwarf stars represent the most common endpoint of stellar evolution. In fact, about 90% of all stars will end up as white dwarfs. Their high temperatures and low luminosities imply that they are small — only about the size of the Earth (R e = 0.009R⊙). The mean radius for white dwarfs is R = 0.01 R⊙ (see the first table).

New white dwarf stars in the Sloan Digital Sky Survey Data Release 10 [PDF]
Monthly Notices of the Royal Astronomical Society, 2015 We report the discovery of 9088 new spectroscopically confirmed white dwarfs and subdwarfs in the Sloan Digital Sky Survey Data Release 10. We obtain Teff, log g and mass for hydrogen atmosphere white dwarf stars (DAs) and helium atmosphere white dwarf ...

Eddington’s theory of stars was a great success. To recall, this theory was predicated on the assumption that stars are globes of ideal gas in radiative equilibrium. The spectacular agreement between many of the predictions of this theory and observations lulled astronomers into thinking that that last word on the subject had been said.

White Dwarfs and Neutron Stars
2004This chapter on the physics of compact objects begins with a section on white dwarfs. It will be shown that the famous Chandrasekhar equation is just the relativistic Thomas–Fermi equation. For white dwarfs the Thomas–Fermi approximation is ideally justified. For neutron stars the general relativistic stellar structure equations are needed.
