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…
Unveiling the Multifaceted GRB 200613A: Prompt Emission Dynamics, Afterglow Evolution, and the Host Galaxy's Properties
Shao-Yu Fu, Dong Xu, Wei-Hua Lei +17
We present our optical observations and multi-wavelength analysis of the GRB\,200613A detected by \texttt{Fermi} satellite. Time-resolved spectral analysis of the prompt -ray em…
