When will T Coronae Borealis next erupt as a nova? Constraints from recurrence, orbital phase, and accretion-state evolution
Songpeng Pei, Xiaowan Zhang, Renzhi Su +6
T Coronae Borealis (T CrB) is the nearest symbiotic recurrent nova and is now intensively monitored for its next eruption. We combine three constraints on the eruption time: histor…
Lack of Significant Orbital-Phase Locking in the Active Phases of the Recurrent Nova T CrB
Songpeng Pei, Xiaowan Zhang, Renzhi Su +6
T Coronae Borealis (T CrB) is a symbiotic recurrent nova (RN) that exhibits both nova eruptions and long-term active phases resembling superoutbursts and normal outbursts. Motivate…
Diffuse gamma-ray emissions around the stellar cluster Berkeley 59
Ziwei Ou, Xiaolong Yang, Songpeng Pei
We report a detailed analysis on the young stellar cluster Berkeley 59 using Fermi-LAT. Using up-to-date source catalog and background models, we found significant extended GeV emi…
4HWC J20293641: a Pulsar Wind Nebula Powered by PSR J20303641?
Ziwei Ou, Jie Wang, Songpeng Pei
4HWC J2029+3641 is a newly discovered point source detected by HAWC, with no previously identified TeV counterpart. The gamma-ray pulsar PSR J2030+3641, located 0.1 degree from the…
