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…
The dynamical origin of multiple populations in intermediate-age clusters in the Magellanic Clouds
Jongsuk Hong, Richard de Grijs, Abbas Askar +7
Numerical simulations were carried out to study the origin of multiple stellar populations in the intermediate-age clusters NGC 411 and NGC 1806 in the Magellanic Clouds. We perfor…
Mapping the Milky Way with LAMOST II: the stellar halo
Yan Xu, Chao Liu, Xiang-Xiang Xue +9
The radial number density and flattening of the Milky Way's stellar halo is measured with metal-poor ([Fe/H]) K giants from LAMOST DR3, using a nonparametric m…
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…
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…
