The Potential of White Dwarf Cosmochronology
TL;DR: In this article, the status of white dwarfs as cosmochronometers is reviewed and the role of these objects in the evolution of stars is discussed, as well as their ability to constrain the ages of various populations of evolved stars in the Galaxy.
Journal ArticleDOI
An independent method for determining the age of the universe

TL;DR: In this article, an age of 9.3 + or - 2.0 Gyr is derived for the Galactic disk on the basis of comparisons between the sudden drop in the observed luminosity distribution and theoretical evolutionary white dwarf models and allowance for a mean prewhite-dwarf lifetime of 0.3 Gyr.
Journal ArticleDOI
Diffusion coefficients for stellar plasmas
TL;DR: In this paper, a methode approximee de calcul des coefficients de diffusion for des plasmas denses caracteristiques des enveloppes de naines blanches is presented.
Journal ArticleDOI
A Driving Mechanism for the Newly Discovered Class of Pulsating Subdwarf B Stars
Stéphane Charpinet,Gilles Fontaine,Pierre Brassard,Pierre Chayer,Forrest J. Rogers,Carlos A. Iglesias,B. Dorman,B. Dorman +7 more
TL;DR: In this article, it was shown that pulsation modes are driven through an opacity bump due to a local enhancement of the iron abundance in the envelopes of sdB stars, which provides a natural explanation for the instabilities found in the newly discovered class of pulsating sdB star.
