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).

Annual Review of Astronomy and Astrophysics, 1980
The violated rule to which Professor Eddington referred was the mass luminosity relation for dwarf stars. The "strange objects" had the exceed ingly low luminosities of the faint red dwarfs, yet their colors were quite bluish. Thus, they came to be called white dwarfs.

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.

The Internal Temperature of White Dwarf Stars
Nature, 1931IT has recently been discovered by S. Chandrasekhar,1 B. Swirles,2 and R. C. Majumdar,3 independently, that the opacity of a degenerate gas is very small compared with what would be computed for a classical gas at the same density and temperature, the ratio being an inverse power of Sommerfeld's degeneracy-criterion parameter.

The Pulsating White Dwarf Stars
Publications of the Astronomical Society of the Pacific, 2008We present a summary of what is currently known about the three distinct families of isolated pulsating white dwarfs. These are the GW Vir stars (He/C/O-atmosphere stars with Teff 120,000 K), the V777 Her stars (He-atmosphere, Teff 25,000 K), and the ZZ Ceti stars (H-atmosphere, Teff 12,000 K), all showing multiperiodic luminosity variations caused by ...

Reports on Progress in Physics, 1990
White dwarf stars, compact objects with extremely high interior densities, are the most common end product in the evolution of stars. The authors review the history of their discovery, and of the realisation that their structure is determined by the physics of the degenerate electron gas.

Asteroseismology of white dwarf stars
Journal of Physics: Condensed Matter, 1998An understanding of the white dwarf stars is central to much of astrophysics, from the structure and evolution of stars to the age and history of the large ensembles of stars that we call galaxies. They are of great potential interest from the standpoint of physics as well, because they offer a chance to study matter under extreme conditions not yet ...
