Angular momentum variation of the Milky Way thick disk: The dependence of chemical abundance and the evidence on inside-out formation scenario
Guozhen Hu, Zhengyi Shao, Lu Li
We investigate the angular momentum of mono-abundance populations (MAPs) of the Milky Way thick disk by using a sample of 26,076 giant stars taken from APOGEE DR17 and Gaia EDR3. T…
MaNGA 8313-1901: gas accretion observed in a blue compact dwarf galaxy?
Mengting Ju, Jun Yin, Rongrong Liu +13
Gas accretion is an important process in the evolution of galaxies, but it has limited direct observational evidences. In this paper, we report the detection of a possible ongoing…
Quantifying chemical and kinematical properties of Galactic disks
Guozhen Hu, Zhengyi Shao
We aim to quantify the chemical and kinematical properties of the Galactic disks with a sample of 119,558 giant stars having abundances and 3D velocities taken or derived from the…
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…
Gaia Parallax of Milky Way Globular Clusters -- A Solution of Mixture Model
Zhengyi Shao, Lu Li
We have established a mixture model approach to derive the parallax of the Milky Way globular clusters. It avoids the problem of cluster membership determination and provides a com…
The substructure and halo population of the Double Cluster and Persei
Jing Zhong, Li Chen, M. B. N. Kouwenhoven +3
In order to study the stellar population and possible substructures in the outskirts of Double Cluster and Persei, we investigate using the GAIA DR2 data a sky area of abou…
