A New Generation of Cool White Dwarf Atmosphere Models. IV. Revisiting the Spectral Evolution of Cool White Dwarfs [PDF]

open access: yesAstrophysical Journal, 2019
As a result of competing physical mechanisms, the atmospheric composition of white dwarfs changes throughout their evolution, a process known as spectral evolution.

White Dwarfs [PDF]

open access: yesInternational Astronomical Union Colloquium, 1994
It is the intention of this review to explain what white dwarfs are and why it is interesting to study them, and why the H+2molecule is of special interest.The evolution, from start to finish, of a star of mass less than about 2 solar masses (M⊙), can roughly be summarized as follows:–A cloud of gas contracts from the interstellar medium until hydrogen

A magnetic white dwarf in a detached eclipsing binary [PDF]

open access: yes, 2013
SDSS J030308.35+005444.1 is a close, detached, eclipsing white dwarf plus M dwarf binary which shows a large infrared excess which has been interpreted in terms of a circumbinary dust disc.

White Dwarf Stars [PDF]

open access: yesInternational Journal of Modern Physics: Conference Series, 2017
White dwarf stars are the final stage of most stars, born single or in multiple systems. We discuss the identification, magnetic fields, and mass distribution for white dwarfs detected from spectra obtained by the Sloan Digital Sky Survey up to Data Release 13 in 2016, which lead to the increase in the number of spectroscopically identified white ...

The Canada–France Imaging Survey: Reconstructing the Milky Way Star Formation History from Its White Dwarf Population [PDF]

open access: yesAstrophysical Journal, 2019
As the remnants of stars with initial masses ≲8 M⊙, white dwarfs contain valuable information on the formation histories of stellar populations. In this paper, we use deep, high-quality, u-band photometry from the Canada–France Imaging Survey, griz ...

A Chondritic Solar Neighborhood

open access: yesThe Planetary Science Journal, 2023
A persistent question in exoplanet demographics is whether exoplanetary systems form from similar compositional building blocks to our own. Polluted white dwarf stars offer a unique way to address this question, as they provide measurements of the bulk ...

HST Spectra of GW Librae: A Hot Pulsating White Dwarf in a Cataclysmic Variable [PDF]

open access: yes, 2002
We have obtained Hubble Space Telescope UV spectra of the white dwarf in GW Lib, the only known non-radially pulsating white dwarf in a cataclysmic variable, and the first known DAZQ variable. The UV light curve reveals large amplitude (10%) pulsationsin
