The Spectroscopic Binaries from LAMOST Medium-Resolution Survey (MRS). I. Searching for Double-lined Spectroscopic Binaries (SB2s) with Convolutional Neural Network
Bo Zhang, Ying-Jie Jing, Fan Yang +13
We developed a convolutional neural network (CNN) model to distinguish the double-lined spectroscopic binaries (SB2s) from others based on single exposure medium-resolution spectra…
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…
