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…
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…
Event Rate Density and Luminosity Function of Newborn-Magnetar-Driven X-Ray Transients from Neutron Star Binary Mergers
Le Zou, Ji-Gui Cheng, Rui-Chong Hu +2
X-ray transients (XTs) driven by newborn magnetars from mergers of neutron star binaries (NSBs) were occasionally detected in the narrow-field {\it Chandra} Deep Field-South survey…
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…
Neutron Star Mergers as the Dominant Contributor to the Production of Heavy -Process Elements
Meng-Hua Chen, Li-Xin Li, Qiu-Hong Chen +2
The discovery of the radioactively powered kilonova AT2017gfo, associated with the short-duration gamma-ray burst GRB 170817A and the gravitational wave source GW170817, has provid…
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…
Super-Eddington Accretion as a Possible Scenario to Form GW190425
W. T. Zhang, Z. H. T. Wang, J. -P. Zhu +7
On 2019 April 25, the LIGO/Virgo Scientific Collaboration detected a compact binary coalescence, GW190425. Under the assumption of the binary neutron star (BNS), the total mass of…
Merging binary black holes formed through double-core evolution
Y. Qin, R. -C. Hu, G. Meynet +5
To date, various formation channels of merging events have been heavily explored with the detection of nearly 100 double black hole (BH) merger events reported by the LIGO-Virgo-KA…
