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…
