Empirically Predicted Absolute Magnitudes for Red Clump Stars in Mephisto and CSST Filters
Zheng Yu, Bing-Qiu Chen, Xiao-Wei Liu
Red clump (RC) stars are reliable standard candles for studying the structure and evolution of the Milky Way. In this study, we present empirical calibrations of RC absolute magnit…
The Stellar Disk Structure Rrevealed by the Mono-age Populations of the LAMOST Red Clump Sample
Zheng Yu, Bingqiu Chen, Jianhui Lian +2
Understanding the structure of the Galactic disk is crucial for understanding the formation and evolutionary history of the Milky Way. This study examines the structure of the Gala…
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…
Mapping the Galactic disk with the LAMOST and Red clump sample: V: On the origin of the "young" [/Fe]-enhanced stars
Weixiang Sun, Yang Huang, Haifeng Wang +8
Using a sample of nearly 140,000 primary red clump stars selected from the LAMOST and surveys, we have identified a large sample of "young" [/Fe]-enhanced stars with stel…
Mapping the Galactic disk with the LAMOST and Gaia red clump sample: IV: the kinematic signature of the Galactic warp
X. -Y. Li, Y. Huang, B. -Q. Chen +5
Using a sample of nearly 140,000 red clump stars selected from the LAMOST and Gaia Galactic surveys, we have mapped mean vertical velocity in the - plane f…
Characterizing Some Gaia Alerts with LAMOST and SDSS
Z. Huo, M. Dennefeld, X. Liu +2
Gaia is regularly producing Alerts on objects where photometric variability has been detected. The physical nature of these objects has often to be determined with the complementar…
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…
Mapping the three-dimensional multi-band extinction and diffuse interstellar bands in the Milky Way with LAMOST
Haibo Yuan, Xiaowei Liu, Maosheng Xiang +4
With modern large scale spectroscopic surveys, such as the SDSS and LSS-GAC, Galactic astronomy has entered the era of millions of stellar spectra. Taking advantage of the huge spe…
