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…
First double red giant Algol system with active mass transfer
Mikhail Kovalev, Hailiang Chen, Sufen Guo +7
Double red giant stars are very important for studies of the stability of mass transfer, common-envelope evolution, and the formation of double white dwarfs with short orbital peri…
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…
Revisiting atmospheric Roche lobe overflow in symbiotic binaries
Tan Liu, Natalia Ivanova, Philipp Podsiadlowski +5
Classical binary evolution models predict dynamically unstable mass transfer in symbiotic stars with high mass ratios, leading to a common envelope. However, many observed S-type s…
Three-Dimensional Simulations of Type Ia Supernova Remnants I: Effects of a Main-Sequence Companion Star
Jingxiao Luo, Gilles Ferrand, Zhengwei Liu +2
Type Ia supernovae (SNe Ia) serve as one of cosmic standard candles, but their exact progenitor channel is still an open question. SNe Ia commonly come from binary star evolution.…
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…
