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…

Lightcurve Features of Magnetar-Powered Superluminous Supernovae with Gravitational-Wave Emission and High-Energy Leakage
Jinghao Zhang, Yacheng Kang, Jiahang Zhong +4
Superluminous supernovae (SLSNe) are a distinct class of stellar explosions, exhibiting peak luminosities 10-100 times brighter than those of normal SNe. Their extreme luminosities…

Mini-supernovae from white dwarf-neutron star mergers: Viewing-angle-dependent spectra and lightcurves
Yacheng Kang, Jin-Ping Zhu, Lijing Shao +3
Unstable mass transfer may occur during white dwarf-neutron star (WD-NS) mergers, in which the WD can be tidally disrupted and form an accretion disk around the NS. Such an accreti…
