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…
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…
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…
