The recent discovery of two pulsating, compact stellar remnants intertwined in a binary system has uncovered a system never-before observed in our Universe, and will offer new avenues for studying the exotic objects involved.
The number and luminosity distribution of white dwarfs stars can be used to help figure out the past history of the Galactic halo.
In today’s Astrophysical Classic, we hark back to 1987 and the introduction of a new method determining the age of the universe through the use of white dwarf stars.
Kepler finds the signature of a transiting white dwarf. Instead blocking the light of its companion star, the white dwarf magnifies it, creating a light curve that periodically brightens.
Archival data are able to place constraints on the origin of supernova 2011fe.
The authors present the discovery of a new hot carbon-atmosphere white dwarf with a strong magnetic field. This discovery might help illuminate the origins of a recently found class of white dwarfs.
