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…
The Importance of Galaxy-Wide Star Formation in Driving Winds at z~1
Weichen Wang, Susan A. Kassin, S. M. Faber +11
In this work, we study winds for a representative sample of 86 star-forming galaxies (SFGs) at z~1 with , by measuring the Mg II line profiles…
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…
Stable Case BB/BC Mass Transfer to Form GW190425-like Massive Binary Neutron Star Mergers
Ying Qin, Jin-Ping Zhu, Georges Meynet +14
On April 25th, 2019, the LIGO-Virgo Collaboration discovered a Gravitational-wave (GW) signal from a binary neutron star (BNS) merger, i.e., GW190425. Due to the inferred large tot…
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…
Formation of GW230529 from Isolated Binary Evolution
Jin-Ping Zhu, Rui-Chong Hu, Yacheng Kang +4
In this {\em{Letter}}, we explore the formation of the mass-gap black hole-neutron star (mgBHNS) merger detected in gravitational wave (GW) event, i.e., GW230529, from the isolated…
A Channel to Form Fast-spinning Black Hole-Neutron Star Binary Mergers as Multimessenger Sources. II. Accretion-induced Spin-up
Zhen-Han-Tao Wang, Rui-Chong Hu, Ying Qin +7
In this work, we investigate an alternative channel for the formation of fast-spinning black hole-neutron star (BHNS) binaries, in which super-Eddington accretion is expected to oc…
Statistical Properties of X-Ray Bursts from SGR J1935+2154 Detected by Insight-HXMT
Wen-Long Zhang, Xiu-Juan Li, Yu-Peng Yang +5
As one class of the most important objects in the universe, magnetars can produce a lot of different frequency bursts including X-ray bursts. In \cite{2022ApJS..260...24C}, 75 X-ra…
Formation of Lower Mass-gap Black Hole--Neutron Star Binary Mergers through Super-Eddington Stable Mass Transfer
Jin-Ping Zhu, Ying Qin, Zhen-Han-Tao Wang +3
Super-Eddington accretion of neutron stars (NSs) has been suggested both observationally and theoretically. In this paper, we propose that NSs in close-orbit binary systems with co…
