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…
Rediscovering the Galactic outer disk with LAMOST data
Chao Liu, Yan Xu, Haifeng Wang +1
From the derived stellar density profile using LAMOST giant stars, we find that the Galactic disk does not show truncation or break, but smoothly transit to the halo from 19 kpc. T…
The peculiar in-plane velocities in the outer disc of the Milky Way
Hai-Jun Tian, Chao Liu, Jun-Chen Wan +9
We present the peculiar in-plane velocities derived from the LAMOST red clump stars, which are purified and separated by a novel approach into two groups with different ages. The s…
Red Clump stars from LAMOST II: the outer disc of the Milky Way
Jun-chen Wan, Chao Liu, Li-cai Deng +1
We present stellar density maps of the Galactic outer disc with red clump stars from the LAMOST data. These samples are separated into younger (mean age ~ 2.7 Gyr) and older (mean…
The age-kinematical features in the Milky Way outer disk
Chao Liu, Hai-Jun Tian, Jun-Chen Wan
We derive the mean velocity components at various Galactocentric radii from 8 to 14 kpc using about 40,000 red clump stars observed in the LAMOST survey. We find that the vertical…
Mapping the Milky Way with LAMOST I: Method and overview
Chao Liu, Yan Xu, Jun-Chen Wan +8
We present a statistical method to derive the stellar density profiles of the Milky Way from spectroscopic survey data, taking into account selection effects. We assume that the se…
The peculiar velocities in the Galactic outer disk--hints of the elliptical disk and the perturbation of the spiral structures
Hai-Jun Tian, Chao Liu, Jun-Chen Wan +7
We present the peculiar in-plane velocities derived from the LAMOST red clump stars. From the variations of the in-plane velocity with the Galactocentric radius for the young and o…
The K giant stars from the LAMOST survey data II: the Hercules stream in radial migration
Chao Liu, Xiao-Yan Chen, Jun Yin +11
We estimate the age for the individual stars located at the lower part of the red giant branch from the LAMOST DR2 K giant sample. Taking into account the selection effects and the…
Red Clump Stars from the LAMOST data I: identification and distance
Junchen Wan, Chao Liu, Licai Deng +5
We present a sample of about 120,000 red clump candidates selected from the LAMOST DR2 catalog based on the empirical distribution model in the effective temperature vs. surface gr…
