The local spiral arm in the LAMOST-Gaia common stars?
Chao Liu, You-Gang Wang, Juntai Shen +7
Using the LAMOST-Gaia common stars, we demonstrate that the in-plane velocity field for the nearby young stars are significantly different from that for the old ones. For the young…
A sample of metal-poor galaxies identified from the LAMOST spectral survey
Yulong Gao, Jianhui Lian, Xu Kong +8
We present a sample of 48 metal-poor galaxies at selected from 92,510 galaxies in the LAMOST survey. These galaxies are identified for their detection of the auroral em…
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…
