The white dwarf cooling sequence of NGC 6791: a unique tool for stellar evolution
E. García-Berro, S. Torres, I. Renedo +5
NGC 6791 is a well-studied, metal-rich open cluster that is so close to us that can be imaged down to luminosities fainter than that of the termination of its white dwarf cooling s…
Evolution of white dwarf stars with high-metallicity progenitors: the role of 22Ne diffusion
Leandro G. Althaus, Enrique García-Berro, Isabel Renedo +3
Motivated by the strong discrepancy between the main sequence turn-off age and the white dwarf cooling age in the metal-rich open cluster NGC 6791, we compute a grid of white dwarf…
New chemical profiles for the asteroseismology of ZZ Ceti stars
L. G. Althaus, A. H. Córsico, A. Bischoff-Kim +4
We compute new chemical profiles for the core and envelope of white dwarfs appropriate for pulsational studies of ZZ Ceti stars. These profiles are extracted from the complete evol…
A white dwarf cooling age of 8 Gyr for NGC 6791 from physical separation processes
Enrique García-Berro, Santiago Torres, Leandro G. Althaus +6
NGC 6791 is a well studied open cluster1 that it is so close to us that can be imaged down to very faint luminosities. The main sequence turn-off age (~8 Gyr) and the age derived f…
New cooling sequences for old white dwarfs
Isabel Renedo, Leandro G. Althaus, Marcelo M. Miller Bertolami +4
We present full evolutionary calculations appropriate for the study of hydrogen-rich DA white dwarfs. This is done by evolving white dwarf progenitors from the zero age main sequen…
