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…
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…
Probing the Galactic Halo with RR Lyrae Stars -- V. Chemistry, Kinematics, and Dynamically Tagged Groups
Jonathan Cabrera Garcia, Timothy C. Beers, Yang Huang +9
We employ a sample of 135,873 RR Lyrae stars (RRLs) with precise photometric-metallicity and distance estimates from the newly calibrated ------[Fe/H] and …
The Circular Velocity Curve of the Milky Way from 5 to 25 kpc using luminous red giant branch star
Yuan Zhou, Xinyi Li, Yang Huang +1
We present a sample of 254,882 luminous red giant branch (LRGB) stars selected from the APOGEE and LAMOST surveys. By combining photometric and astrometric information from the 2MA…
Photometric metallicity and distance estimates for 136,000 RR Lyrae stars from Gaia DR3
Xin-Yi Li, Yang Huang, Gao-Chao Liu +2
We present a sample of 135,873 RR Lyrae stars (RRLs) with precise photometric-metallicity and distance estimates from our newly calibrated [Fe/H]/[Fe/H…
Discovery of A candidate Hypervelocity star originated from the Sagittarius Dwarf Spheroidal galaxy
Yang Huang, Qingzheng Li, Huawei Zhang +5
In this letter, we report the discovery of an intriguing HVS (J1443+1453) candidate that is probably from the Sagittarius Dwarf Spheroidal galaxy (Sgr dSph). The star is an old and…
The distances of 61 PGCCs in the Second Galactic Quadrant
H. -L. Guo, B. -Q. Chen, G. -X. Li +5
Determining the distances to the Planck Galactic cold clumps (PGCCs) is crucial for the measurement of their physical parameters and the study of their Galactic distribution. Based…
Three-Dimensional Distribution of the Interstellar Dust in the Milky Way
H. -L. Guo, B. -Q. Chen, H. -B. Yuan +6
We present a three-dimensional (3D) extinction map of the southern sky. The map covers the SkyMapper Southern Survey (SMSS) area of 14,000 and has spatial re…
Mapping the Galactic disk with the LAMOST and Red clump sample: V: On the origin of the "young" [/Fe]-enhanced stars
Weixiang Sun, Yang Huang, Haifeng Wang +8
Using a sample of nearly 140,000 primary red clump stars selected from the LAMOST and surveys, we have identified a large sample of "young" [/Fe]-enhanced stars with stel…
Mapping the Galactic disk with the LAMOST and Gaia red clump sample: IV: the kinematic signature of the Galactic warp
X. -Y. Li, Y. Huang, B. -Q. Chen +5
Using a sample of nearly 140,000 red clump stars selected from the LAMOST and Gaia Galactic surveys, we have mapped mean vertical velocity in the - plane f…
Mapping the Galactic disk with the LAMOST and Gaia Red clump sample: I: precise distances, masses, ages and 3D velocities of 140000 red clump stars
Yang Huang, Ralph Schonrich, Huawei Zhang +10
We present a sample of 140,000 primary red clump (RC) stars of spectral signal-to-noise ratios higher than 20 from the LAMOST Galactic spectroscopic surveys, selected based…
