New evolutionary calculations for the Born Again scenario
M. M. Miller Bertolami, L. G. Althaus, A. M. Serenelli +1
We present evolutionary calculations aimed at describing the born-again scenario for post-AGB remnant stars of 0.5842 and 0.5885 \msun. Results are based on a detailed treatment of…
Evolutionary and pulsational properties of low-mass white dwarf stars with oxygen cores resulting from close binary evolution
L. G. Althaus, A. H. Corsico, A. Gautschy +3
The present work is designed to explore the evolutionary and pulsational properties of low-mass white dwarfs with carbon/oxygen cores. In particular, we follow the evolution of a 0…
New evolutionary models for massive ZZ Ceti stars: I. First results for their pulsational properties
L. G. Althaus, A. M. Serenelli, A. H. Corsico +1
We present new and improved evolutionary calculations for carbon-oxygen white dwarf (WD) stars appropriate for the study of massive ZZ Ceti stars. We follow the complete evolution…
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…
