Evolution of low-mass He stars and implications for electron-capture supernova formation in close binaries
Jun-Qian Li, Ying Qin, Zi-Yuan Wang +3
The evolution of low-mass helium (He) stars (--) with neutron-star (NS) companions in close binaries has been extensively studied, but the combined effects of…
Mass-Ratio Reversal as an Alternative to Hierarchical Mergers for GW241011
Rui-Chong Hu, Ying Qin, Bing Zhang
Recent gravitational-wave (GW) observations have revealed binary black hole (BBH) mergers with both extreme mass ratios and large effective spin parameters (). GW2410…
How do the LIGO-Virgo-KAGRA's Heavy Black Holes Form? No evidence for core-collapse Intermediate-mass black holes in GWTC-4
Fan-Xiao-Yu Xia, Yuan-Zhu Wang, Ying Qin
We investigate the population properties of binary black holes (BBHs) from the LIGO-Virgo-KAGRA collaboration, focusing especially on those in the high-mass range, using the newly…
Diagnosing the Properties and Evolutionary Fates of Black Hole and Wolf-Rayet X-ray Binaries as Potential Gravitational Wave Sources for the LIGO-Virgo-KAGRA Network
Zi-Yuan Wang, Ying Qin, Georges Meynet +7
IC 10 X-1, NGC 300 X-1, and Cyg X-3 constitute a unique class of X-ray binaries in which a stellar-mass black hole (BH) accretes material from a Wolf-Rayet (WR). These systems are…
Reassessing the Spin of Second-born Black Holes in Coalescing Binary Black Holes and Its Connection to the chi_eff-q Correlation
Zi-Yuan Wang, Ying Qin, Rui-Chong Hu +3
The mass ratio q and effective inspiral spin chi_eff of binary black hole (BBH) mergers in GWTC-4.0 show a weaker anti-correlation than in GWTC-3.0, motivating investigation of its…
Origin of Black Hole Spin in Lower-Mass-Gap Black Hole-Neutron Star Binaries
Ying Qin, Zhen-Han-Tao Wang, Georges Meynet +8
During the fourth observing run, the LIGO-Virgo-KAGRA Collaboration reported the detection of a coalescing compact binary (GW230529181500) with component masses estimated at…
