A possible formation channel for blue hook stars in globular cluster - II. Effects of metallicity, mass ratio, tidal enhancement efficiency and helium abundance
Zhenxin Lei, Gang Zhao, Aihua Zeng +4
Employing tidally enhanced stellar wind, we studied in binaries the effects of metallicity, mass ratio of primary to secondary, tidal enhancement efficiency and helium abundance on…

A possible formation channel for blue hook stars in globular cluster
Zhenxin Lei, Xuemei Chen, Fenghui Zhang +1
The formation mechanism for blue hook (BHk) stars in globular clusters (GCs) is still unclear. Following one of the possible scenario, named late hot flash scenario, we proposed th…

Effect of Binary Fraction on Horizontal Branch Morphology under Tidally Enhanced Stellar Wind
Zhenxin Lei, Xuemei Chen, Xiaoyu Kang +2
Tidally enhanced stellar wind may affect horizontal branch (HB) morphology in globular clusters (GCs) by enhancing the mass loss of primary star during binary evolution. Lei et al.…
