Modelling quantum aspects of disruption of a white dwarf star by a black hole [PDF]
Scientific Reports, 2021 We study the final stages of the evolution of a binary system consisted of a black hole and a white dwarf star. We implement the quantum hydrodynamic equations and carry out numerical simulations.

DE Canum Venaticorum : a bright, eclipsing red dwarf–white dwarf binary [PDF]
Physical Review D, 2007 Context. Close white dwarf–red dwarf binaries must have gone through a common-envelope phase during their evolution. DE CVn is a detached white dwarf–red dwarf binary with a relatively short (∼8.7 h) orbital period.

Stark Broadening and White Dwarfs [PDF]
Open Astronomy, 2011 White dwarf and pre-white dwarfs are the best types of stars for the application of Stark broadening research results in astrophysics, since in the atmospheres of these stars physical conditions are very favorable for this line broadening mechanism - in ...

A Mini-Review of Accreting Pulsating White Dwarfs
Frontiers in Astronomy and Space Sciences, 2021 The discovery in 1998 of a pulsating white dwarf in the cataclysmic variable GW Lib opened up a new avenue of exploration in the asteroseismology of white dwarfs.

Proceedings of Supernovae: lights in the darkness — PoS(SUPERNOVA), 2008 Thermonuclear (type Ia) supernovae are explosions in accreting white dwarfs, but the exact scenario leading to these explosions is still unclear. An important step to clarify this point is to understand the behaviour of accreting white dwarfs in close binary systems.

EPJ Web of Conferences, 2017 The Sloan Digital Sky Survey has allowed us to increase the number of known white dwarfs by a factor of five and consequently the number of known pulsating white dwarfs also by a factor of five. It has also led to the discovery of new types of variable white dwarfs, as the variable hot DQs, and the pulsating Extremely Low Mass white dwarfs.

White Dwarf and Pre-White Dwarf Pulsations [PDF]
AIP Conference Proceedings, 2009 In this review I describe the basic properties of white dwarfs and their pulsations. I then discuss some of the areas in which the pulsations can provide meaningful results, such as internal chemical profiles, possible emission of “exotic” particles, planet detection, crystallization, convection, accretion, and cosmochronology.

White Dwarf Crystallization [PDF]
International Astronomical Union Colloquium, 1994 AbstractThe inclusion of a detailed treatment of solidification processes in the cooling theory of carbon–oxygen white dwarfs is of crucial importance for the determination of their luminosity function. Carbon–oxygen separation at crystallization yields delays larger than 2 Gyr to cool down to luminosities corresponding to the observed cut–off.

The Astronomical Journal, 2023 Excess infrared flux from white dwarf stars is likely to arise from a dusty debris disk or a cool companion. In this work, we present near-infrared spectroscopic observations with Keck/MOSFIRE, Gemini/GNIRS, and Gemini/Flamingos-2 of seven white dwarfs ...
