The rotation curve and mass distribution of M31
Xiangwei Zhang, Bingqiu Chen, Pinjian Chen +2
To gain a better understanding of the Andromeda galaxy M31 and its role in the Local Group, measuring its mass precisely is essential. In this work, we have constructed the rotatio…
Mapping the Galactic disk with the LAMOST and Gaia Red clump sample: VIII: Mapping the kinematics of the Galactic disk using mono-age and mono-abundance stellar populations
Weixiang Sun, Yang Huang, Han Shen +5
We present a comprehensive study of the kinematic properties of the different Galactic disk populations, as defined by the chemical abundance ratios and stellar ages, across a larg…
The Galactic spiral structure as revealed by O- and early B-type stars
Chen Bingqiu, Huang Yang, Hou Ligang +7
We investigate the morphology and kinematics of the Galactic spiral structure based on a new sample of O- and early B-type stars. We select 6,858 highly confident OB star candidate…
On the kinematic signature of the Galactic warp as revealed by the LAMOST-TGAS data
Yang Huang, R. Schönrich, Xiaowei Liu +6
Using a sample of about 123,000 stars with accurate 3D velocity measurements from the LAMOST-TGAS data, we confirm the kinematic signature of the Galactic warp found by Schönrich &…
Member stars of the GD1 tidal stream from the SDSS, LAMOST and Gaia surveys
Yang Huang, Xiaowei Liu, Bingqiu Chen +5
With the photometric data from the SDSS survey, the spectroscopic data from the SDSS/SEGUE and the LAMOST surveys, and the astrometric data from the Gaia DR2, we have identified 71…
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…
