Two Earliest Optical-UV Tidal Disruption Events Hidden in the SDSS DR7 Catalog Unveiled by the Transformer-Based Spectrum Classifier
Ranfang Zheng, Zheyu Lin, Xu Kong +3
Optical spectroscopic features are decisive in the current identification of optical-UV tidal disruption events (TDEs). Regarding that the TDE estimated occurrence rate is $10^{-5}…
The atmospheric extinction curve at Lenghu site
Jin-Sheng Qiu, Xiao-Hui Xu, Qing-Feng Zhu +11
In this study, we use a dedicated spectroscopic telescope to carry out low-resolution measurements of the optical atmospheric extinction curve at Lenghu astronomical site in Qingha…
Illuminating the Mass Gap Through Deep Optical Constraint on a Neutron Star Merger Candidate S250206dm
Zhengyan Liu, Zelin Xu, Ji-an Jiang +35
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…
The 2.5-meter Wide Field Survey Telescope Real-time Data Processing Pipeline I: From raw data to alert distribution
Minxuan Cai, Zelin Xu, Lulu Fan +13
The Wide Field Survey Telescope (WFST) is a dedicated photometric surveying facility built jointly by the University of Science and Technology of China (USTC) and the Purple Mounta…
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…
