Photometric Distances for Metal-poor Giants and a Search for Hypervelocity Stars with LAMOST DR13 and Gaia DR3
Shuai Xu, Haibo Yuan, Bowen Huang +2
Hypervelocity stars (HVSs) are stars with velocities high enough to escape the Milky Way, but their identification depends sensitively on distance estimates, particularly for dista…
Towards optimal photometric calibration of digital astronomical plates with deep learning
Mingyang Ma, Haibo Yuan, Lin Yang +8
Photometric calibration of digitized photographic plates is commonly modeled with separable magnitude-, color-, and position-dependent terms, but this separability can break down w…
GSED: The Galactic Stellar Extinction Database
Baisong Zhang, Bingqiu Chen, Dongwei Fan +9
Reliable extinction correction is essential for nearly all astrophysical studies within the Galaxy. We present the Galactic Stellar Extinction Database (GSED, https://nadc.china-vo…
The Stellar Abundances and Galactic Evolution Survey (SAGES). V. The First Data Release of the DDO51 Band
Qiqian Zhang, Zhou Fan, Gang Zhao +20
We present the first public data release of DDO51 band from the Stellar Abundances and Galactic Evolution Survey (SAGES), based on Nanshan One-meter Wide-field Telescope (NOWT) obs…
Homogenization of the Stetson Photometry with the BEST Database
Zhirui Li, Bowen Huang, Kai Xiao +5
As one of the most widely recognized high-quality standard stars, the Stetson standards have been extensively used as a photometric reference for calibrating other surveys. In this…
A Large and Precise All-Sky Photometric Standard Star Dataset Across More Than 200 Passbands
Kai Xiao, Yang Huang, Haibo Yuan +12
High-precision photometric standard stars play a key role in enabling accurate photometric calibration and advancing various fields of astronomy. However, due to limitations in cal…
