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…
