Forward Modeling of the Sct Star V1790 Ori: , , Resolution and Non-adiabatic Effects

Xiaoya Sun, Antonio García Hernández, Zhaoyu Zuo +5

We investigate the role of large separation, rotational correction order, structural resolution, and non-adiabatic effects in modelling the rotating Scuti star V1790 Ori. From…

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…

New constraints on cosmic anisotropy from galaxy clusters using an improved dipole fitting method

Jianping Hu, Chao Geng, Xuandong Jia +3

The cosmological principle, as the cornerstone of the standard cosmological model, requires that the Universe be homogeneous and isotropic on large scales. As a fundamental assumpt…

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…
