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…
On the structure of open clusters: geometric vs geomantic
Lu Li, Zhengyi Shao
Understanding our place in the universe is an eternal quest. Through the analysis of the 3D structures of 66 nearby open clusters using Gaia DR3 data, we discovered an intriguing p…
Mass-Dependent Radial Distribution of Single and Binary Stars in the Pleiades and their Dynamical Implications
Rongrong Liu, Zhengyi Shao, Lu Li
The Pleiades is a young open cluster that has not yet dynamically relaxed, making it an ideal target to observe various internal dynamical effects. By employing a well-defined samp…
Photometric Determination of Unresolved Main-sequence Binaries in the Pleiades: Binary Fraction and Mass Ratio Distribution
Rongrong Liu, Zhengyi Shao, Lu Li
Accurate determination of binary fractions () and mass ratio () distributions is crucial for understanding the dynamical evolution of open clusters. We present an imp…
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…
