Stellar chromospheric activity and age relation from open clusters in the LAMOST Survey
Jiajun Zhang, Jingkun Zhao, Terry D. Oswalt +5
We identify member stars of more than 90 open clusters in the LAMOST survey. With the method of Fang et al.(2018), the chromospheric activity (CA) indices logR'CaK for 1091 member…
Tracing Kinematic and Chemical Properties of Sagittarius Stream by K-Giants, M-Giants, and BHB stars
Chengqun Yang, Xiang-Xiang Xue, Jing Li +12
We characterize the kinematic and chemical properties of 3,000 Sagittarius (Sgr) stream stars, including K-giants, M-giants, and BHBs, select from SEGUE-2, LAMOST, and SDSS s…
Detecting the Sagittarius stream with LAMOST DR4 M giants \& Gaia DR2
Jing Li, Chao Liu, Xiangxiang Xue +4
We use LAMOST DR4 M giants combined with Gaia DR2 proper motions and ALLWISE photometry to obtain an extremely pure sample of Sagittarius (Sgr) stream stars. Using TiO5 and CaH spe…
The substructure and halo population of the Double Cluster and Persei
Jing Zhong, Li Chen, M. B. N. Kouwenhoven +3
In order to study the stellar population and possible substructures in the outskirts of Double Cluster and Persei, we investigate using the GAIA DR2 data a sky area of abou…
