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

The paper combines historical eruption intervals, orbital phase information, and recent accretion‑state changes to give conditional probabilities and monitoring windows for the nex…

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…

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…
