R-process nucleosynthesis from magnetar giant flares in neutron star--white dwarf mergers: A unified picture for peculiar long gamma-ray bursts
Shu-Qing Zhong, Long Li, Le Zou +3
Peculiar long gamma-ray bursts (GRBs), exemplified by GRBs 211211A and 230307A, exhibit a long-duration multi-component prompt emission, an X-ray plateau in their afterglow, and a…
Is gamma-ray burst polarization from photosphere emission?
Yan-Zhi Meng, Shu-Qing Zhong, Jia-Hong Gu +2
Context: Despite more than half a century of research, the dominant radiation mechanism of gamma-ray burst (GRB) prompt emission remains unsolved. Some progress has been made throu…
Observed Steep and Shallow Spectra, Narrow and Broadband Spectra, Multi-frequency Simultaneous Spectra, and Statistical Fringe Spectra in Fast Radio Bursts: Various Faces of Intrinsic Quasi-periodic Spectra?
Shu-Qing Zhong, Wen-Jin Xie, Jia-Hong Gu
In this paper, through analysis, modelings, and simulations, we show that if the spectra of fast radio bursts (FRBs) are intrinsically quasi-periodic spectra, likely produced by co…
The Value-added Catalog of OB Stars in LAMOST DR7
Zhicun Liu, Wenyuan Cui, Jiajia Gu +4
In this work, we update the catalog of OB stars based on the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) data release 7 and modified the OB stars selection c…
Gravitational waves associated with the r-mode instability from neutron star-white dwarf mergers
Shu-Qing Zhong, Yan-Zhi Meng, Jia-Hong Gu
Neutron star-white dwarf (NS-WD) binaries evolve into either ultra-compact X-ray binaries undergoing stable mass transfer or direct mergers by unstable mass transfer. While much at…
