Nucleosynthesis during the merger of white dwarfs and the origin of R Coronae Borealis stars
(Iop Publishing, 2011-08)
Many hydrogen-deficient stars are characterized by surface abundance patterns that are hard to reconcile with conventional stellar evolution. Instead, it has been suggested that they may represent the result of a merger ...
Updated Evolutionary Sequences for Hydrogen-deficient White Dwarfs
(IOP Publishing, 2017-04)
We present a set of full evolutionary sequences for white dwarfs with hydrogen-deficient atmospheres. We take into account the evolutionary history of the progenitor stars, all the relevant energy sources involved in the ...
3D kinematics of white dwarfs from the SPY project. II.
(EDP SCIENCES S A, 2006-02)
We present the kinematics of a sample of 398 DA white dwarfs from the SPY project (ESO SN Ia Progenitor surveY) and discuss kinematic criteria for distinguishing of thin-disk, thick-disk, and halo populations. This is the ...
