Evolution of wide O star binaries through their LBV stage. Population synthesis with mass-ejection-driven orbital evolution
Xiao-Tian Xu, Philipp Podsiadlowski, Norbert Langer +6
Context. Long-period Wolf-Rayet (WR) star binaries produced by mass transfer are predicted to be abundant, but are observationally rare. This yields constraints on the evolution of…
Thermal-timescale accretion does not always yield critical rotation in mass gainers
Chen Wang, Mike Y. M. Lau, Xiang-Dong Li +7
Binary evolution plays a central role in producing rapidly rotating stars. Previous studies have shown that mass gainers in binaries can reach critical rotation after accreting onl…
Stable mass transfer in massive binaries leading to merging black holes
Xiao-Tian Xu, Norbert Langer, Jakub Klencki +2
The vast majority of massive binary systems in the universe is evidently unsuited to produce merging binary black holes. However, several narrow evolutionary paths of isolated mass…
A statistical study of type II outbursts of XRPs: Brighter accreting pulsars rotate faster
Shan-Shan Weng, Xiao-Tian Xu, Han-Long Peng +6
X-ray pulsars (XRPs) consist of a magnetized neutron star (NS) and an optical donor star. The NS accretes matter from the donor star producing pulsed X-ray emission. In most cases…
