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…
The Vertical Displacement of the Milky Way Disk
Heidi Jo Newberg, Yan Xu
An oscillating vertical displacement of the Milky Way, with a wavelength of about 8 kpc and and amplitude of about 100 pc (increasing with distance from the Galactic center) is obs…
