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…
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.…
Unraveling the mysteries of supernovae with SKA+VLBI
Tao An, Zhengwei Liu, Ailing Wang +6
Supernovae (SNe) drive cosmic chemical enrichment and shape galactic feedback, yet the link between progenitors and explosion outcomes remains poorly constrained because the earlie…
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…
