Evolution and colours of helium-core white dwarf stars: the case of low metallicity progenitors
A. M. Serenelli, L. G. Althaus, R. D. Rohrmann +1
The present work is designed to explore the evolution of helium-core white dwarf (HeWD) stars for the case of metallicities much lower than the solar one (Z=0.001 and Z=0.0002). Ev…
Improved synthetic spectra of helium-core white dwarf stars
R. D. Rohrmann, A. M. Serenelli, L. G. Althaus +1
We examine the emergent fluxes from helium-core white dwarfs following their evolution from the end of pre-white dwarf stages down to advanced cooling stages. For this purpose, we…
On mode trapping in pulsating DA white dwarf stars
O. G. Benvenuto, A. H. Corsico, L. G. Althaus +1
The present work is designed to explore the effects of the time-dependent element diffusion on the mode trapping properties of DA white dwarf models with various thickness of the h…
The mode trapping properties of full DA white dwarf evolutionary models
A. H. Corsico, L. G. Althaus, O. G. Benvenuto +1
An adiabatic, non-radial pulsation study of a 0.563 M_sun DA white dwarf model is presented on the basis of new evolutionary calculations performed in a self-consistent way with th…
Time dependent diffusion in pulsating white dwarf stars: Asteroseismology of G117-B15A
O. G. Benvenuto, A. H. Corsico, L. G. Althaus +1
We study the structural characteristic of the variable DA white dwarf G117B-15A by applying the methods of asteroseismology. For such a purpose, we construct white dwarf evolutiona…
The Effects of Element Diffusion on the Pulsational Properties of Variable DA White Dwarf Stars
A. H. Corsico, O. G. Benvenuto, L. G. Althaus +1
We explore the effects of element diffusion due to gravitational settling and thermal and chemical diffusion on the pulsational properties of DA white dwarfs. To this end, we emplo…
