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…
WD0433+270: an old Hyades stream member or an Fe-core white dwarf?
S. Catalan, I. Ribas, J. Isern +1
G39-27/289 is a common proper motion pair formed by a white dwarf (WD0433+270) and a main-sequence star (BD+26 730) that apparently has been classified as a member of the Hyades op…
The initial-final mass relationship from white dwarfs in common proper motion pairs
S. Catalan, J. Isern, E. Garcia-Berro +3
The initial-final mass relationship of white dwarfs, which is poorly constrained, is of paramount importance for different aspects in modern astrophysics. From an observational per…
Evidence for a merger of binary white dwarfs: the case of GD 362
E. Garcia-Berro, P. Loren-Aguilar, A. G. Pedemonte +4
GD 362 is a massive white dwarf with a spectrum suggesting a H-rich atmosphere which also shows very high abundances of Ca, Mg, Fe and other metals. However, for pure H-atmospheres…
