Open Clusters are born and evolve along the Milky Way plane, on them is imprinted the history of the Galactic disc, including the chemical and dynamical evolution. Chemical and dyn…
New insights into the structure of open clusters in the Gaia era
Jing Zhong, Li Chen, Yueyue Jiang +2
With the help of Gaia data, it is noted that in addition to the core components, there are low-density outer halo components in the extended region of open clusters. To study the e…
New Open Cluster candidates Found in Galactic Disk Using Gaia DR2/EDR3 Data

We characterize the kinematic and chemical properties of 589 Galactic Anticenter Substructure Stars (GASS) with K-/M- giants in Integrals-of-Motion space. These stars likely includ…
Modelling unresolved binaries of open clusters in color-magnitude diagram. I. method and application of NGC3532
Lu Li, Zhengyi Shao, Zhao-Zhou Li +3
The binary properties of open clusters place crucial constraints on star formation theory and clusters' dynamical evolution. We develop a comprehensive approach that models the col…
Exploring open cluster properties with Gaia and LAMOST
Jing Zhong, Li Chen, Di Wu +3
In Gaia DR2, the unprecedented high-precision level reached in sub-mas for astrometry and mmag for photometry. Using cluster members identified with these astrometry and photometry…
LAMOST Medium-Resolution Spectroscopic Survey (LAMOST-MRS): Scientific goals and survey plan
Chao Liu, Jianning Fu, Jianrong Shi +38
Since September 2018, LAMOST starts a new 5-year medium-resolution spectroscopic survey (MRS) using bright/gray nights. We present the scientific goals of LAMOST-MRS and propose a…
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…
