Evolution of the stellar mass function in open clusters from a universal and unsegregated initial state
Lu Li, Zhaozhou Li, Zhengyi Shao +2
The stellar mass function (MF) and its spatial variation (mass segregation) within star clusters encode signatures of early formation physics and subsequent secular evolution. Yet,…
The Hierarchical Structure of the Open Cluster NGC 752
Delong Jia, Heng Yu, Zhengyi Shao +1
The structure of open clusters provides key insights into their evolution and the dynamics of the Milky Way. Using Gaia DR3 data, we applied a hierarchical clustering algorithm to…
The destiny of open cluster NGC 6530: past and future
Delong Jia, Heng Yu, Zhengyi Shao +1
Studying the structures of open clusters is crucial for understanding stellar evolution and galactic dynamics. Based on Gaia DR3 data, we apply the hierarchical clustering algorith…
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…
Exploring open cluster properties with Gaia and LAMOST
Jing Zhong, Li Chen, Di Wu +3
In Gaia DR2, the unprecedented high-precision level reached in sub-mas for astrometry and mmag for photometry. Using cluster members identified with these astrometry and photometry…
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…
