GW Librae: a unique laboratory for pulsations in an accreting white dwarf
(2016)
Non-radial pulsations have been identified in a number of accreting white dwarfs in cataclysmic variables. These stars offer insight into the excitation of pulsation modes in atmospheres with mixed compositions of hydrogen, ...
White dwarf stars
(Asociación Argentina de Astronomía, 2009)
White dwarfs are the most common end-product of stellarevolution, and as such contain valuable information about the evolutionof individual stars as well as about the star formation history andsubsequent evolution in our ...
The evolution of white dwarfs resulting from helium-enhanced, low-metallicity progenitor stars
(EDP Sciences, 2017-01)
Context. Some globular clusters host multiple stellar populations with different chemical abundance patterns. This is particularly true for ω Centauri, which shows clear evidence of a helium-enriched subpopulation characterized ...
Di scovery of a T dwarf + white dwarf binary system
(2011)
We present the discovery of the first T dwarf + white dwarf binary system LSPM 1459+0857AB, confirmed through common proper motion and spectroscopy. The white dwarf is a high proper motion object from the LSPM catalogue ...
The formation of ultra-massive carbon-oxygen core white dwarfs and their evolutionary and pulsational properties
(EDP Sciences, 2021-02)
Context. The existence of ultra-massive white dwarf stars, MWD & 1.05 M, has been reported in several studies. These white dwarfs are relevant for the role they play in type Ia supernova explosions, the occurrence of ...
