The gravitational wave (GW) event S250206dm, as the first well-localized neutron star merger candidate potentially located in the mass gap, presented a unique opportunity to probe…
Asteroseismology study of a new faint ZZ Ceti J053009.62+594557.0 discovered in WFST
Yang Yonghui, Guo Jincheng, Lin Jie +16
In this work, we present a detailed asteroseismological analysis of WFST J053009.62+594557.0, a newly discovered faint pulsating white dwarf by the Wide Field Survey Telescope (WFS…
TTC: Transformer-based TDE Classifier for the Wide Field Survey Telescope (WFST)
Ranfang Zheng, Zheyu Lin, Xu Kong +22
We propose the Transformer-based Tidal disruption events (TDE) Classifier (\texttt{TTC}), specifically designed to operate effectively with both real-time alert streams and archiva…
The Statistical Analysis Of The Galactic Open Clusters' Structure
Jin-Sheng Qiu, Zhen Wan, Xu-Zhi Li +5
We present a systematic investigation of 1,481 Galactic open clusters (OCs) through the application of the Limepy dynamical model, from which we derive the fundamental structural p…
The Faintest, Extremely Variable X-ray Tidal Disruption Event from a Supermassive Black Hole Binary?
Mengqiu Huang, Yongquan Xue, Shuo Li +30
Tidal disruption events (TDEs), which occur when stars enter the tidal radii of supermassive black holes (SMBHs) and are subsequently torn apart by their tidal forces, represent in…
A Star's Death by a Thousand Cuts: The Runaway Periodic Eruptions of AT2023uqm
Yibo Wang, Tingui Wang, Shifeng Huang +37
Stars on bound orbits around a supermassive black hole may undergo repeated partial tidal disruption events (rpTDEs), producing periodic flares. While several candidates have been…
Introduction to the Chinese Space Station Survey Telescope (CSST)
CSST Collaboration, Yan Gong, Haitao Miao +119
The Chinese Space Station Survey Telescope (CSST) is an upcoming Stage-IV sky survey telescope, distinguished by its large field of view (FoV), high image quality, and multi-band o…
A Glimpse of Satellite Galaxies in the Milky Way with the 2.5-meter Wide Field Survey Telescope (WFST): Bootes III and Draco
Chao Yang, Zhizheng Pan, Min Fang +34
We carry out deep imaging of the Milky Way satellite galaxies, Bootes III and Draco, with WFST as one pilot observing program to demonstrate the capability of WFST. Combining catal…
