Mapping the three-dimensional dust extinction toward the supernova remnant S147 - the S147 dust cloud
B. -Q. Chen, X. -W. Liu, J. -J. Ren +7
We present a three dimensional (3D) extinction analysis in the region toward the supernova remnant (SNR) S147 (G180.0-1.7) using multi-band photometric data from the Xuyi Schmidt T…
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 LAMOST Survey of Background Quasars in the Vicinity Fields of the M 31 and M 33 - III. Results from the 2013 Regular Survey
Zhi-Ying Huo, Xiao-Wei Liu, Mao-Sheng Xiang +7
In this work, we report new quasars discovered in the vicinity fields of the Andromeda (M31) and Triangulum (M33) galaxies with the LAMOST (Large Sky Area Multi-Object Fiber Spectr…
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…
