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…
Existence of Tidal Tails for the Globular Cluster NGC 5824
Yong Yang, Jing-Kun Zhao, Miho N. Ishigaki +5
Context. Several dynamically cold streams have been associated with certain globular clusters (GCs) based on orbital energies and angular momenta. Some of these streams are surpris…
Milky Way Mass with K Giants and BHB Stars Using LAMOST, SDSS/SEGUE, and Gaia: 3D Spherical Jeans Equation and Tracer Mass Estimator
Sarah A. Bird, Xiang-Xiang Xue, Chao Liu +8
We measure the enclosed Milky Way mass profile to Galactocentric distances of and kpc using the smooth, diffuse stellar halo samples of Bird et al. The samples ar…
Influence of the Gaia-Sausage-Enceladus on the density shape of the Galactic stellar halo revealed by halo K giants from the LAMOST survey
Wenbo Wu, Gang Zhao, Xiang-Xiang Xue +2
We present a study of the influence of the Gaia-Sausage-Enceladus (GSE) on the density shape of the Galactic stellar halo using 11624 K giants from the LAMOST survey. Every star is…
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…
