Hot Subdwarfs From the Roche Lobe Overflow Channel

摘要：

There are various channels for the formation of hot subdwarfs. In this study, we concentrate on the formation and evolution of hot subdwarf binaries through the stable Roche lobe overflow (RLOF) channel of intermediate-mass binaries. We aim at displaying the properties of hot subdwarfs and their progenitors from the stable RLOF channel, so that we can understand the formation and evolution of hot subdwarfs comprehensively. By taking into account recent star formation in young clusters, we propose that a fraction of hot subdwarfs is present in young clusters.
