Extreme PeV accelerator associated with GRS 1915+105
Zhen Cao, F. Aharonian, Y. X. Bai +322
Microquasars, binary systems featuring relativistic jets, have emerged as sources for particle acceleration beyond PeV energies. We present a study of the broadband -ray emissi…
Can dwarf novae produce type Ia supernovae?
Ruijie Li, Chengyuan Wu, Zhibin Dai +1
Accreting white dwarfs (WDs) are considered one of the most promising progenitor candidates for Type Ia supernovae (SNe Ia). Dwarf novae (DNe), a subclass of cataclysmic variables…
Evidence of Long-Lived Powerful Gyrosynchrotron Radio Emission in the Close Binary FF UMa
Ruijie Gao, Jun Yang, Yang Gao +7
RS Canum Venaticorum (RS CVn) close binaries, characterized by tidal locking, rapid rotations, and strong magnetic fields, are ideal laboratories for high-resolution radio observat…
A New Algol-type Binary with an Accretion disk
Tongyu He, Jiao Li, Xiaobin Zhang +10
We present a comprehensive photometric and spectroscopic analysis of the Algol-type binary \textit{Gaia} DR3 1892576067672499328. We identified the system as a spectroscopic binary…
GOTO065054+593624: a 8.5 mag amplitude dwarf nova identified in real time via Kilonova Seekers
T. L. Killestein, G. Ramsay, M. Kennedy +62
Dwarf novae are astrophysical laboratories for probing the nature of accretion, binary mass transfer, and binary evolution -- yet their diverse observational characteristics contin…
