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…
Photometric Metallicities for 367,324 stars of Omega Centauri
Xue Lu, Haibo Yuan, Bowen Huang +2
Omega Centauri is the most massive and chemically complex multi-population globular cluster with a wide metallicity range that has been extensively studied photometrically and spec…
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…
Stellar Loci. IX. Estimation of Stellar Parameters from CSST-like Photometry
Xue Lu, Haibo Yuan, Kai Xiao +5
The China Space Station Telescope (CSST) will conduct a deep and wide imaging survey in the NUV-, u-, g-, r-, i-, z-, and y-bands. In this work, using theoretical data synthesized…
