High Resolution Spectroscopic Follow-up Observation Results for 13 EMP Candidates Selected by Narrow-band Photometry
Huiling Chen, Yang Huang, Huawei Zhang +1
Extremely metal-poor (EMP; [Fe/H] < -3.0) stars preserve key information about the earliest stages of Galactic chemical evolution. Based on a training set of spectroscopic metallic…
An Old, Low-mass, Metal-poor Hypervelocity Star Candidate Consistent with a Galactic Center Origin
Shunhong Deng, Yang Huang, Haozhu Fu +4
We report the discovery of DESI-HVS1, a hypervelocity star (HVS) candidate identified from DESI DR1 spectroscopy and Gaia DR3 astrometry. DESI-HVS1 is an old, low-mass, metal-poor…
Filter Design for Estimating the Stellar Metallicity of Metal-poor Stars from Gaia XP Spectra
Ruifeng Shi, Yang Huang, Kai Xiao +5
The estimation of stellar atmospheric parameters for large-scale samples, particularly metal-poor stars, is a cornerstone of Galactic archaeology. In this work, we optimized a phot…
Three-dimensional reddening maps of the Magellanic Clouds constructed by RR Lyrae stars
Shunxuan He, Yang Huang
We present the first three-dimensional reddening maps of the Large and Small Magellanic Clouds (LMC and SMC) constructed using fundamental-mode RR Lyrae stars from the OGLE-IV surv…
Search for Distant Hypervelocity Star Candidates Using RR Lyrae Stars
Haozhu Fu, Yang Huang, Huawei Zhang
Hypervelocity stars (HVSs) are stars with velocities exceeding their local escape velocities. Searching for HVSs and studying their origins can be an important way to study the pro…
Photometric-Metallicity and Distance Estimates for 70,000 RR Lyrae Stars from the Zwicky Transient Facility
Shunxuan He, Yang Huang, XinYi Li +5
Utilizing Zwicky Transient Facility (ZTF) data and existing RR Lyrae stars (RRLs) catalogs, this study achieves the first calibration of the a…
Identifying the Galactic Substructures in 5D Space Using All-sky RR Lyrae Stars in Gaia DR3
Shenglan Sun, Fei Wang, Huawei Zhang +9
Motivated by the vast gap between photometric and spectroscopic data volumes, there is great potential in using 5D kinematic information to identify and study substructures of the…
On the Performances of Estimating Stellar Atmospheric Parameters from CSST Broad-band Photometry
Ruifeng Shi, Yang Huang, Xinyi Li +1
Deriving atmospheric parameters of a large sample of stars is of vital importance to understand the formation and evolution of the Milky Way. Photometric surveys, especially those…
Probing the Galactic halo with RR Lyrae stars -- IV. On the Oosterhoff dichotomy of RR Lyrae stars
Shan Zhang, Gaochao Liu, Yang Huang +8
We use 3653 (2661 RRab, 992 RRc) RR Lyrae stars (RRLs) with 7D (3D position, 3D velocity, and metallicity) information selected from SDSS, LAMOST, and Gaia EDR3, and divide the sam…
