Pulsations driven by the $ε$ -mechanism in post-merger remnants: first results

Marcelo M. Miller Bertolami, Alejandro H. Córsico, Xianfei Zhang +2

Helium-rich subdwarfs are a rare subclass of hot subdwarf stars which constitute a small and inhomogeneous group showing varying degrees of helium enrichment. Only one star, LS IV…

Can R CrB stars form from the merger of two helium white dwarfs?

Xianfei Zhang, C. Simon Jeffery

Due to orbital decay by gravitational-wave radiation, some close-binary helium white dwarfs are expected to merge within a Hubble time. The immediate merger products are believed t…
