英文摘要Hot subdwarf (SD) stars provide a valuable opportunity to study stellar evolution, binary evolution, and element diffusion. In the conventional binary evolution scenario, SDs are believed to be the stripped cores of red giants. Here, we propose a new formation process for massive hot subdwarfs which involves a CE ejection with an AGB star. This alternative pathway can explain helium-rich SDs with log(n(He)/n(H)) > -1 due to the partial hydrogen burning in the envelope.
