Hubble Space Telescope Observations of UV Oscillations in WZ Sagittae During the Decline from Outburst [PDF]

, 2003
We present a time series analysis of Hubble Space Telescope observations of WZ Sge obtained in 2001 September, October, November and December as WZ Sge declined from its 2001 July superoutburst.

A White Dwarf Catalog from LAMOST DR11 Using Deep Learning

The Astrophysical Journal Supplement Series
White 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.

A Gravitational-wave-detectable Candidate Type Ia Supernova Progenitor

The Astrophysical Journal
Type Ia supernovae (SNe Ia), critical for studying cosmic expansion, arise from thermonuclear explosions of white dwarfs, but their precise progenitor pathways remain unclear.

Revisiting the Impact of Axions in the Cooling of White Dwarfs

, 2012
It has been shown that the shape of the luminosity function of white dwarfs can be a powerful tool to check for the possible existence of DFSZ-axions. In particular, Isern et al.

Low Frequency Gravitational Waves from White Dwarf MACHO Binaries [PDF]

, 2000
The possibility that Galactic halo MACHOs are white dwarfs has recently attracted much attention. Using the known properties of white dwarf binaries in the Galactic disk as a model, we estimate the possible contribution of halo white dwarf binaries to ...

Violent mergers revisited: The origin of the fastest stars in the Galaxy

Astronomy & Astrophysics
Binary systems of two carbon-oxygen white dwarfs are one of the most promising candidates for the progenitor systems of Type Ia supernovae. Violent mergers, where the primary white dwarf ignites when the secondary white dwarf smashes into it while being ...

Models for the soft X-ray emission of post-outburst classical novae

, 2005
A hydrostatic and stationary white dwarf envelope model has been developed for the study of the post-outburst phases of classical novae and their soft X-ray emission.

Weighing The Options: The Unseen Companion in LAMOST J2354 is Likely a Massive White Dwarf

The Open Journal of Astrophysics
LAMOST J235456.73+335625 (J2354) is a binary system hosting a $\sim 0.7~\rm M_\odot$ K dwarf and a $\sim 1.4~\rm M_\odot$ dark companion, supposedly a neutron star, in a 0.48d orbit.
