MeV Gamma-Ray Lines from Radioactive Nuclei in Magnetar Giant Flares
Wu-Zimo Qiumu, Meng-Hua Chen, Qiu-Hong Chen +4
The rapid neutron-capture process (r-process) is widely regarded as the dominant mechanism responsible for the synthesis of heavy elements in the universe, yet its astrophysical si…
Novae breves from magnetar giant flares: Potential probes of neutron star crusts
Jiahang Zhong, Qiu-Hong Chen, Yacheng Kang +4
Matter ejected from the magnetar crust during giant flares (GFs) may undergo -process nucleosynthesis, producing short-lived optical transients termed "novae breves". Although i…
Neutron Star-White Dwarf Merger as One Possible Optional Source of Kilonova-like Emission: Implications for GRB 211211A
Xiao-Xuan Liu, Hou-Jun Lü, Qiu-Hong Chen +2
Long-duration GRB 211211A, which lacked an associated supernova at such a low redshift , but was associated with a possible kilonova emission, has attracted great attentio…
Kilonova Emission from Neutron Star Mergers with Different Equations of State
Wu-Zimo Qiumu, Meng-Hua Chen, Qiu-Hong Chen +1
Kilonova is an optical-infrared transient powered by the radioactive decay of heavy nuclei from binary neutron star mergers. Its observational characteristics depend on the mass an…
