Subdwarf B stars from the common envelope ejection channel

Abstract:

Context

Subdwarf B stars (sdB) are important to stellar evolutionary theory and asteroseismology, and are crucial to our understanding of the structure and evolution of the Galaxy. From the canonical binary scenario, the majority of sdBs are produced from low-mass stars with degenerate cores where helium is ignited in a way of flashes. Due to numerical difficulties, the models of produced sdBs are generally constructed from more massive stars with non-degenerate cores. This leave...
