摘要 Binary population synthesis(BPS),an approach to evolving millions of stars(including binaries) simultaneously,plays a crucial role in our understanding of stellar physics,the structure and evolution of galaxies,and cosmology.We proposed and developed a BPS approach,and used it to investigate the formation of many peculiar stars such as hot subdwarf stars,progenitors of type la supernovae,barium stars, CH stars,planetary nebulae,double white dwarfs,blue stragglers,contact binaries,etc.We also established an evolution population synthesis(EPS) model,the Yunnan Model,which takes into account binary interactions for the first time.We applied our model for the origin of hot subdwarf stars in the study of elliptical galaxies and explained their far-UV radiation. Binary population synthesis (BPS), an approach to evolving millions of stars (including binaries) simultaneously, plays a crucial role in our understanding of stellar physics, the structure and evolution of galaxies, and cosmology. We proposed and developed a BPS approach, and used it to investigate the formation of many peculiar stars such as hot subdwarf stars, progenitors of type la supernovae, barium stars, CH stars, planetary nebulae, double white dwarfs, blue stragglers, contact binaries, etc. We also established an evolution population synthesis (EPS) model, the Yunnan Model, which takes into account binary interactions for the first time. We applied our model for the origin of hot subdwarf stars in the study of elliptical galaxies and explained their far-UV radiation.
