The double helium-white dwarf channel for the formation of AM CVn binaries
Xianfei Zhang, Jinzhong Liu, C. Simon Jeffery +2
Most close double helium white dwarfs will merge within a Hubble time due to orbital decay by gravitational-wave radiation. However, a significant fraction with low mass ratios wil…
Evolution models of helium white dwarf--main sequence star merger remnants
Xianfei Zhang, Philip D. Hall, C. Simon Jeffery +1
It is predicted that orbital decay by gravitational-wave radiation and tidal interaction will cause some close-binary stars to merge within a Hubble time. The merger of a helium-co…
Hydrogen in hot subdwarfs formed by double helium white dwarf mergers
Philip D. Hall, C. Simon Jeffery
Isolated hot subdwarfs might be formed by the merging of two helium-core white dwarfs. Before merging, helium-core white dwarfs have hydrogen-rich envelopes and some of this hydrog…
Core radii and common-envelope evolution
Philip D. Hall, Christopher A. Tout
Many classes of objects and events are thought to form in binary star systems after a phase in which a core and companion spiral to smaller separation inside a common envelope (CE)…
Planetary nebulae after common-envelope phases initiated by low-mass red giants
Philip D. Hall, Christopher A. Tout, Robert G. Izzard +1
It is likely that at least some planetary nebulae are composed of matter which was ejected from a binary star system during common-envelope (CE) evolution. For these planetary nebu…
