Discovery of two new hypervelocity stars from the LAMOST spectroscopic surveys
Yang Huang, Xiaowei Liu, Huawei Zhang +7
We report the discovery of two new unbound hypervelocity stars (HVSs) from the LAMOST spectroscopic surveys. They are respectively a B2V type star of ~ 7 M with a Gal…
Ages and masses of million Galactic disk main sequence turn-off and sub-giant stars from the LAMOST Galactic spectroscopic surveys
Maosheng Xiang, Xiaowei Liu, Jianrong Shi +10
We present estimates of stellar age and mass for 0.93 million Galactic disk main sequence turn-off and sub-giant stars from the LAMOST Galactic Spectroscopic Surveys. The ages and…
On the metallicity gradients of the Galactic disk as revealed by LSS-GAC red clump stars
Yang Huang, Xiao-Wei Liu, Hua-Wei Zhang +10
Using a sample of over 70, 000 red clump (RC) stars with -% distance accuracy selected from the LAMOST Spectroscopic Survey of the Galactic Anti-center (LSS-GAC), we study t…
The evolution of stellar metallicity gradients of the Milky Way disk from LSS-GAC main sequence turn-off stars: a two-phase disk formation history?
M. -S. Xiang, X. -W. Liu, H. -B. Yuan +8
We use 297 042 main sequence turn-off stars selected from the LSS-GAC to determine the radial and vertical gradients of stellar metallicity of the Galactic disk in the anti-center…
The LAMOST Spectroscopic Survey of Globular Clusters in M 31 and M 33. I. Catalog and new identifications
B. -Q. Chen, X. -W. Liu, M. -S. Xiang +12
We present a catalog of 908 objects observed with the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) in the vicinity fields of M31 and M33, targeted as globular…
Galactic Disk Bulk Motions as Revealed by the LSS-GAC DR2
Ning-Chen Sun, Xiao-Wei Liu, Yang Huang +10
We report a detailed investigation of the bulk motions of the nearby Galactic stellar disk, based on three samples selected from the LSS-GAC DR2: a global sample containing 0.57 mi…
