Correlation between the two-armed spiral in the -- plane and moving groups
Yan Xu, Chao Liu, Chengdong Li +5
We use a cross-matched sample of 3.7 million stars from Gaia DR3 and LAMOST DR7 to investigate the velocity substructures in the Milky Way disk. The median radial velocity as…
LAMOST meets Gaia: The Galactic Open Clusters
Xiaoting Fu, Angela Bragaglia, Chao Liu +14
Open Clusters are born and evolve along the Milky Way plane, on them is imprinted the history of the Galactic disc, including the chemical and dynamical evolution. Chemical and dyn…
Exploring the Galactic Anticenter substructure with LAMOST & Gaia DR2
Jing Li, Xiang-Xiang Xue, Chao Liu +12
We characterize the kinematic and chemical properties of 589 Galactic Anticenter Substructure Stars (GASS) with K-/M- giants in Integrals-of-Motion space. These stars likely includ…
Differential rotation of the halo traced by the K-giant stars
Hao Tian, Chao Liu, Yougang Wang +4
We use K-giant stars selected from the LAMOST DR5 to study the variation of the rotational velocity of the galactic halo at different space positions. Modelling the rotational velo…
Rotating halo traced by the K giant stars from LAMOST and Gaia
Hao Tian, Chao Liu, Yan Xu +1
With the help of Gaia DR2, we are able to obtain the full 6-D phase space information for stars from LAMOST DR5. With high precision of position, velocity, and metallicity, the rot…
Mapping the Milky Way with LAMOST III: Complicated spatial structure in the outer disc
Hai-Feng Wang, Chao Liu, Yan Xu +2
We present {complexity} of the Galactic outer disc {by fitting the stellar volume densities of the red giant branch stars with a two-disc component model}. {The discs are confirmed…
