Carbon-Enhanced Metal-Poor Star Candidates in the Milky Way from J-PLUS and S-PLUS

Jihye Hong, Timothy C. Beers, Yang Huang +4

Recent large-scale multi-band photometric surveys now enable elemental-abundance estimates for millions of stars with accuracies approaching those of low- to medium-resolution spec…

A Metallicity Catalog of Very Metal-poor Main-sequence Turn-off and Red Giant Stars from LAMOST DR10

Xiangyu Li, Huiling Chen, Yang Huang +4

We present a catalog of 8,440 candidate very metal-poor (VMP; [Fe/H] < -2.0) main-sequence turn-off (MSTO) and red giant stars in the Milky Way, identified from low-resolution spec…

Identification of BHB stars using Synthetic SkyMapper colors from Gaia XP spectra

Guozhen Hu, Yang Huang, Wenyuan Cui +9

Blue horizontal-branch (BHB) stars are ideal tracers for mapping the structure of Galactic stellar halo. Traditionally, BHB sample stars are built from large-scale spectroscopic su…

Stellar Parameters for over Fifty Million stars from SMSS DR4 and Gaia DR3

Yang Huang, Timothy C. Beers

We present an updated catalog of stellar parameters, including effective temperature, luminosity classification, and metallicity, for over fifty million stars from the SkyMapper So…

The Stellar Abundances and Galactic Evolution Survey (SAGES). II. Machine Learning-Based Stellar parameters for 21 million stars from the First Data Release

Hongrui Gu, Zhou Fan, Gang Zhao +14

Stellar parameters for large samples of stars play a crucial role in constraining the nature of stars and stellar populations in the Galaxy. An increasing number of medium-band pho…

Photometric Stellar Parameters for 195,478 Kepler Input Catalog (KIC) Stars

Bowen Zhang, Yang Huang, Timothy C. Beers +9

The stellar atmospheric parameters and physical properties of stars in the Kepler Input Catalog (KIC) are of great significance for the study of exoplanets, stellar activity, and a…
