Constructing the Milky Way Stellar Halo in the Galactic Center by Direct Orbit Integration
Chengqun Yang, Ling Zhu, Behzad Tahmasebzadeh +2
The halo stars on highly radial orbits should inevitably pass the center regions of the Milky Way. Under the assumption that the stellar halo is in dynamical equilibrium and axisym…
Revisit NGC 5466 Tidal Stream with , SDSS/SEGUE and LAMOST
Yong Yang, Jing-Kun Zhao, Miho N. Ishigaki +5
By mining the data from EDR3, SDSS/SEGUE DR16 and LAMOST DR8, 11 member stars of the NGC 5466 tidal stream are detected and 7 of them are newly identified. To reject contami…
Vertical structure of Galactic disk kinematics from LAMOST K giants
Ping-Jie Ding, Xiang-Xiang Xue, Chengqun Yang +3
We examine the vertical structure of Galactic disk kinematics over a Galactocentric radial distance range of and up to away from the Galactic pla…
Self-consistent Stellar Radial Velocities from LAMOST Medium-Resolution Survey (MRS) DR7
Bo Zhang, Jiao Li, Fan Yang +12
Radial velocity (RV) is among the most fundamental physical quantities obtainable from stellar spectra and is rather important in the analysis of time-domain phenomena. The LAMOST…
The old moving groups in the field of Taurus
Jiaming Liu, Min Fang, Hao Tian +3
In this work, we present a systematic search for stellar groups in the Taurus field by applying DBSCAN algorithm to the data from Gaia DR2. We find 22 groups, consisting of 8 young…
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…
