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…
Spectral Dataset of Stripped-Envelope Supernovae from the Tsinghua Supernova Group
Danfeng Xiang, Xiaofeng Wang, Jujia Zhang +40
The extent of envelope stripping in the progenitor stars is directly reflected in the diversity of spectral features observed in stripped-envelope supernovae (SESNe). Through exten…
Multi-wavelength study of the pre-eruption dip in the recurrent nova T Coronae Borealis preceding imminent nova eruption
Songpeng Pei, Xiaowan Zhang, Renzhi Su +6
We present a multi-wavelength study of the symbiotic recurrent nova (RN) T Coronae Borealis (T CrB) using Swift Burst Alert Telescope (BAT) / X-Ray Telescope (XRT) / UltraViolet Op…
Temporal variability and obscuration effects in the X-ray emission of classical nova V339 Delphini (Nova Delphini 2013)
Songpeng Pei, Nataly Ospina, Xiaowan Zhang +4
In this study, we present a detailed analysis of public archival soft X-ray data on the classical nova V339 Delphini (Nova Del 2013) during its outburst, obtained using the {\it Ch…
Timing and spectral analysis of GK Persei during the 2010 dwarf nova outburst
Songpeng Pei, Xiaowan Zhang, Qiang Li +3
GK Persei, an old nova and intermediate polar (IP), exhibited a dwarf nova (DN) outburst in 2010. This outburst was extensively observed by the Neil Gehrels Swift Observatory, begi…
