A Helium-shell Burning Blue Horizontal Branch Star Produced from Common Envelope Evolution
Jiao Li, Changqing Luo, Hai-Liang Chen +16
Observationally, blue horizontal branch (BHB) stars are defined as hot stars occupying a characteristic region between the extreme blue horizontal branch and RR Lyrae variables in…
Formation of Extremely Low-mass White Dwarf Binaries Undergoing Enhanced Angular Momentum Loss
Ziqi Zhao, Zhenwei Li, Zhengwei Liu +6
Extremely low-mass white dwarfs (ELM WDs) are helium (He) WDs with masses below , mainly formed through binary interaction. ELM WD binaries typically are forme…
Influence of mass-transfer stability on the formation of post-common-envelope binaries
Yanxu Shi, Hongwei Ge, Zhenwei Li +9
Post-common-envelope binaries are the natural laboratories for constraining the physics of common envelope evolution, which is one of the most uncertain phases in binary stellar ev…
Mass-Orbital Period Distribution of Massive White Dwarfs Formed Through Stable Mass Transfer
Rizhong Zheng, Hongwei Ge, Christopher A Tout +10
White dwarfs (WDs) in binaries can form through either the stable mass-transfer process or common envelope evolution (CEE). Compared to CEE, the stable mass-transfer process can le…
Mass distribution of neutron stars in binary systems
Zhe Hu, GuoLiang Lv, ChunHua Zhu +5
It is known that the mass distribution of the known neutron stars (NSs) exhibits a bimodal pattern. The origin of this distribution remains a subject of debate. We constructed a su…
Adiabatic Mass Loss In Binary Stars. VI. Massive Helium Binary Stars
Lifu Zhang, Hongwei Ge, Zhenwei Li +6
The stability of binary mass transfer is a critical problem for binary evolution. We systematically calculate the adiabatic mass-loss model for naked helium stars with masses rangi…
