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…

Exploring the central engines of gamma-ray bursts from prompt light curves

Xue Zhang, Shuang-Xi Yi, Wei-Hua Lei +6

Hyperaccreting stellar-mass black hole systems are leading candidates for the central engines of gamma-ray bursts (GRBs). Their jets are thought to be powered by either the Blandfo…

Constraining the initial Lorentz factor of gamma-ray bursts under different circumburst mediums

Sheng-Jin Sun, Shuang-Xi Yi, Yuan-Chuan Zou +4

The initial Lorentz factor () plays a crucial role in uncovering the physical characteristics of gamma-ray bursts (GRBs). Previous studies have indicated that the amb…

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…
