Dynamical Models of the Milky Way in Action Space with LAMOST DR8 and GAIA EDR3
Guang-Chen Sun, Qiao Wang, Shude Mao +6
This work explores dynamical models of the Milky Way (MW) by analyzing a sample of 86,109 K giant stars selected through cross-matching the LAMOST DR8 and Gaia EDR3 surveys. Our ea…
Mapping the Milky Way's stellar halo with 2D data
Anda Chen, Zhigang Li, Yougang Wang +3
We propose a new method for measuring the spatial density distribution of the stellar halo of the Milky Way. Our method is based on a pairwise statistic of the distribution of star…
Stellar Dynamical Modeling -- Counting Conserved Quantities
Richard J. Long, Shude Mao, Yougang Wang
Knowing the conserved quantities that a galaxy's stellar orbits conform to is important in helping us understand the stellar distribution and structures within the galaxy. Isolatin…
Classifying globular clusters and applying them to estimate the mass of the Milky Way
GuangChen Sun, Yougang Wang, Chao Liu +3
We combine the kinematics of 159 globular clusters (GCs) provided by the Gaia Early Data Release 3 (EDR3) with other observational data to classify the GCs, and to estimate the mas…
LTD064402+245919: A Subgiant with a 1-3 M Undetected Companion Identified from LAMOST-TD Data
Fan Yang, Bo Zhang, Richard J. Long +11
Single-line spectroscopic binaries recently contribute to the stellar-mass black hole discovery, independently of the X-ray transient method. We report the identification of a sing…
SDSS-IV MaNGA: Stellar M/L gradients and the M/L-colour relation in galaxies
Junqiang Ge, Shude Mao, Youjun Lu +3
The stellar mass-to-light ratio gradient in SDSS band of a galaxy depends on its mass assembly history, which is imprinted in its morphology and gradients of…
