Revisiting the theoretical DBV (V777 Her) instability strip: the MLT theory of convection
A. H. Córsico, L. G. Althaus, M. M. Miller Bertolami +1
We reexamine the theoretical instability domain of pulsating DB white dwarfs (DBV or V777 Her variables). We performed an extensive -mode nonadiabatic pulsation analysis of DB e…
Gravitational settling of 22Ne and white dwarf evolution
E. García--Berro, L. G. Althaus, A. H. Córsico +1
We study the effects of the sedimentation of the trace element 22Ne in the cooling of white dwarfs. In contrast with previous studies, which adopted a simplified treatment of the e…
The age and colors of massive white dwarf stars
L. G. Althaus, E. García-Berro, J. Isern +2
We present evolutionary calculations and colors for massive white dwarfs with oxygen-neon cores for masses between 1.06 and 1.28 Mo. The evolutionary stages computed cover the lumi…
New nonadiabatic pulsation computations on full PG1159 evolutionary models: the theoretical GW Vir instability strip revisited
A. H. Córsico, L. G. Althaus, M. M. Miller Bertolami
We reexamine the theoretical instability domain of pulsating PG1159 stars (GW Vir variables). We performed an extensive g-mode stability analysis on PG1159 evolutionary models with…
Mass-radius relations for massive white dwarf stars
L. G. Althaus, E. García--Berro, J. Isern +1
We present detailed theoretical mass-radius relations for massive white dwarf stars with oxygen-neon cores. This work is motivated by recent observational evidence about the existe…
The formation of DA white dwarfs with thin hydrogen envelopes
L. G. Althaus, M. M. Miller Bertolami, A. H. Córsico +2
We study the formation and evolution of DA white dwarfs, the progenitors of which have experienced a late thermal pulse (LTP) shortly after the departure from the thermally pulsing…
