A Tale of Two Origins: In-Situ versus Accreted Nitrogen-Rich Field Stars in the MW
Yi Qiao, Baitian Tang, José G. Fernández-Trincado +14
Spectroscopic surveys have identified significant numbers of metal-poor nitrogen-rich (N-rich) field stars. These stars are strong candidates for escapees from globular clusters (G…

A catalog of more than 43,000 M giant stars has been selected by Li et al. from the ninth data release of LAMOST. Using the data-driven method SLAM, we obtain the stellar parameter…
A Blind All-sky Search for Star Clusters in Gaia EDR3: 886 Clusters within 1.2 kpc of the Sun
Zhihong He, Kun Wang, Yangping Luo +3
Although previous searches for star clusters have been very successful, many clusters are likely still omitted, especially at high Galactic latitude regions. In this work, based on…
Searching Extra-tidal Features around the Globular Cluster Whiting 1
Jundan Nie, Hao Tian, Jing Li +14
Whiting 1 is a faint and young globular cluster in the halo of the Milky Way, and was suggested to have originated in the Sagittarius spherical dwarf galaxy (Sgr dSph). In this pap…
Exploring the Galactic Anticenter substructure with LAMOST & Gaia DR2
Jing Li, Xiang-Xiang Xue, Chao Liu +12
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…
Exploring the pertubed Milky Way disk and the substructures of the outer disk
Y. Xu, C. Liu, H. Tian +6
The recent discovery of a spiral feature in phase plane in the solar neighborhood implies that the Galactic disk has been remarkably affected by a dwarf galaxy passing thro…
Tracing Kinematic and Chemical Properties of Sagittarius Stream by K-Giants, M-Giants, and BHB stars

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…
Identifying Galactic Halo Substructure in 6D Phase-space Using 13,000 LAMOST K Giants
Chengqun Yang, Xiang-Xiang Xue, Jing Li +6
We construct a large halo K-giant sample by combining the positions, distances, radial velocities, and metallicities of over 13,000 LAMOST DR5 halo K giants with the Gaia DR2 prope…
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…
Revealing the Complicated Story of the Cetus Stream with StarGO
Zhen Yuan, M. C. Smith, Xiang-Xiang Xue +5
We use a novel cluster identification tool StarGO to explore the metal poor ([Fe/H] -1.5) outer stellar halo (d 15 kpc) of the Milky Way using data from Gaia, LAMOST and SD…
A Systematic Study of Hale and Anti-Hale Sunspot Physical Parameters
Jing Li
We present a systematic study of sunspot physical parameters using full disk magnetograms from MDI/SoHO and HMI/SDO. Our aim is to use uniform datasets and analysis procedures to c…
Probing satellite galaxies in the Local Group by using FAST
Jing Li, Yougang Wang, Minzhi Kong +3
The abundance of neutral hydrogen (HI) in satellite galaxies in the Local Group is important for studying the formation history of our Local Group. In this work, we generated mock…
Mapping the Milky Way with LAMOST II: the stellar halo
