Search for L4 Earth Trojan asteroids with the 2.5-meter Wide Field Survey Telescope
Junqiang Lu, Lulu Fan, Shaohan Wang +16
Earth Trojan asteroids (ETAs) are a mysterious population, and dynamically stable ETAs, if primordial, could be "living fossils" of the early solar system. To date, there are only…
WFST Astrometric Calibration -- I. Modeling Global Geometric Distortion with Zernike Polynomials
Chao Yang, Min Fang, Xian Zhong Zheng +21
Accurate modeling of geometric distortion is essential for precise astrometric calibration in wide-field imaging surveys. We present a self-calibration method based on Zernike poly…
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…
Multiwavelength Observations of the Apparently Non-repeating FRB 20250316A
Ye Li, Hui Sun, Lei Qian +72
The physical origin of fast radio bursts (FRBs) remains uncertain. Although multiwavelength observations have been widely conducted, only Galactic FRB~20200428D is associated with…
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…
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…
