1111.6652 (Edward M. Sion)
Edward M. Sion
The article covers the physical properties and evolution of single white
dwarfs ranging in temperature from 20,000K to 200,000 and higher, the hottest
know electron-degenerate stars. After discussing the classification of their
spectra, the author reviews the known properties, parameters, evolutionary
state, as well as persisting and new puzzles regarding all spectroscopic
subclasses of hot white dwarfs: the hot DA white dwarfs, the DAO white dwarfs,
the PG1159 degenerates, the DO white dwarfs, the DB white dwarfs, the DBA white
dwarfs, and the Hot DQ white dwarfs (an entirely new class). The most recent
observational and theoretical advances are brought to bear on the topic.
