贫金属富碳天琴RR变星的形成
《天文学报》2019年第5期54-61,共8页夏晔 张先飞 毕少兰 马旭东 
国家自然科学基金项目(10933002、11703001、11273007)资助
贫金属富碳恒星(Carbon-Enhanced Metal-Poor,CEMP)是研究宇宙早期恒星性质和化学演化的极佳样本,通常认为来自双星.目前发现的贫金属富碳星中有9颗天琴RR变星(RR Lyrae star,RRL),其中至少7颗未表现出任何双星特征.传统双星物质转移模...

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 will survive for a long time as a conseque...

Grids of rotating stellar models with masses between 1.0 and 3.0 M_⊙
《Research in Astronomy and Astrophysics》2013年第5期579-592,共14页Wu-Ming Yang Shao-Lan Bi Xiang-Cun Meng 
supported by the China Postdoctoral Science Foundation(Grant No.20100480222);the National Natural Science Foundation of China(Grant Nos.11273012,11273007,10933002and11003003);the Project of Science and Technology from the Ministryof Education(211102)
We calculated a grid of evolutionary tracks of rotating models with masses between 1.0 and 3.0 M⊙ and resolution δM 〈 0.02 M⊙, which can be used to study the effects of rotation on stellar evolution and on the cha...
