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
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…
Probing cosmic anisotropy from galaxy clusters via the 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…
Tianyu: search for the second solar system and explore the dynamic universe
Fabo Feng, Yicheng Rui, Zhimao Du +32
Giant planets like Jupiter and Saturn, play important roles in the formation and habitability of Earth-like planets. The detection of solar system analogs that have multiple cold g…
