The mass ratio distribution of short period double degenerate stars [PDF]
, 2002 Short period double degenerates (DDs) are close white dwarf - white dwarf binary stars which are the result of the evolution of interacting binary stars.

White Dwarf/M Dwarf Binaries as Single Degenerate Progenitors of Type Ia Supernovae
, 2012 Limits on the companions of white dwarfs in the single degenerate scenario for the origin of Type Ia supernovae (SNIa) have gotten increasingly tight. The only type of non-degenerate stars that survive the limits on the companions of SNIa in SNR 0509-67 ...

The Lowest Mass White Dwarf [PDF]
, 2006 Extremely low mass white dwarfs are very rare objects likely formed in compact binary systems. We present MMT optical spectroscopy of 42 low mass white dwarf candidates serendipitously discovered in a survey for hypervelocity B-type stars.

Measuring the Mass–Radius Relation of White Dwarfs Using Wide Binaries
The Astrophysical JournalMeasuring the mass–radius relation of individual white dwarfs is an empirically challenging task that has been performed for only a few dozen stars. We measure the white dwarf mass–radius relation using the gravitational redshifts and radii of 135 white ...

Orbital Decay in an Accreting and Eclipsing 13.7 Minute Orbital Period Binary with a Luminous Donor
The Astrophysical Journal Letters, 2023 We report the discovery of ZTF J0127+5258, a compact mass-transferring binary with an orbital period of 13.7 minutes. The system contains a white dwarf accretor, which likely originated as a post–common envelope carbon–oxygen (CO) white dwarf, and a warm

Brown Dwarf Companions to White Dwarfs [PDF]
AIP Conference Proceedings, 2011 Brown dwarf companions to white dwarfs are rare, but recent infra-red surveys are slowly reveal- ing examples. We present new observations of the post-common envelope binary WD0137-349, which reveals the effects of irradiation on the ~ 0.05M* secondary, and new observations of GD 1400 which show that it too is a close, post-comon envelope system.

A White Dwarf Catalog from LAMOST DR11 Using Deep Learning
The Astrophysical Journal Supplement SeriesWhite dwarfs, also referred to as degenerate dwarfs, represent the ultimate fate for the majority of stars in the Universe, unless their mass is large enough for them to evolve into black holes or neutron stars.
