On the formation of hot DQ white dwarfs
L. G. Althaus, E. García-Berro, A. H. Córsico +2
We present the first full evolutionary calculations aimed at exploring the origin of hot DQ white dwarfs. These calculations consistently cover the whole evolution from the born-ag…
On the origin of white dwarfs with carbon-dominated atmospheres: the case of H1504+65
L. G. Althaus, A. H. Córsico, S. Torres +1
We explore different evolutionary scenarios to explain the helium deficiency observed in H1504+65, the most massive known PG1159 star. We concentrate mainly on the possibility that…
Evidence of thin helium envelopes in PG1159 stars
L. G. Althaus, A. H. Córsico, M. M. Miller Bertolami +2
We present evidence that PG1159 stars could harbour He--rich envelopes substantially thinner than those predicted by current evolutionary models with current estimates of mass loss…
