A Path to Constraints on Common Envelope Ejection in Massive Binaries: Full Evolutionary Reconstruction of Three Black Hole X-ray Binaries
Zhenwei Li, Dandan Wei, Shi Jia +6
The massive binary common envelope (CE) phase plays a pivotal role in the formation of close black hole/neutron star (BH/NS) binaries, yet significant uncertainties remain in our u…
Formation of Be stars via wind accretion: Case study on Black hole + Be star binaries
Zhenwei Li, Shi Jia, Dandan Wei +5
Be stars are rapidly rotating main-sequence (MS) stars that play a crucial role in understanding stellar evolution and binary interactions. In this letter, we propose a new formati…
Formation of Extremely Low-Mass White Dwarfs in Wide Orbits
Yangyang Zhang, Zhenwei Li, Xuefei Chen
Helium white dwarfs (WDs) with masses less than 0.3 $\rm M_{\sun}$ are known as extremely low-mass WDs (ELM WDs), which cannot be produced by single stellar evolution in theory. Ge…
Constraints on Common Envelope Ejection from Double Helium White Dwarfs
Yangyang Zhang, Zhenwei Li, Xuefei Chen +1
Double helium white dwarfs (He WDs) are one type of gravitational wave source and are greatly important in the studies of binary interaction, particularly in the common envelope (C…
