The evolution of white dwarfs resulting from helium-enhanced, low-metallicity progenitor stars

Abstract

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 sub-population characterized by a helium abundance as high as Y = 0.4 Aims. We present a whole and consistent set of evolutionary tracks from the ZAMS to the… (More)
