The evolution of white dwarfs resulting from helium-enhanced, low-metallicity progenitor stars
(EDP Sciences, 2017-01)
Context. Some globular clusters host multiple stellar populations with different chemical abundance patterns. This is particularly true for ω Centauri, which shows clear evidence of a helium-enriched subpopulation characterized ...
The formation of ultra-massive carbon-oxygen core white dwarfs and their evolutionary and pulsational properties
(EDP Sciences, 2021-02)
Context. The existence of ultra-massive white dwarf stars, MWD & 1.05 M, has been reported in several studies. These white dwarfs are relevant for the role they play in type Ia supernova explosions, the occurrence of ...
