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…
Validating Open Cluster Candidates with Photometric Bayesian Evidence
Lu Li, Zhaozhou Li, Zhengyi Shao
The thousands of open cluster (OC) candidates identified by the Gaia mission are significantly contaminated by false positives from field star fluctuations, posing a major validati…
The MiMO Catalog: Physical Parameters and Stellar Mass Functions of 1,232 Open Clusters from Gaia DR3
Lu Li, Zhengyi Shao, Zhaozhou Li +1
We present a homogeneous catalog of 1,232 open clusters with precisely determined ages, metallicities, distances, extinctions, and stellar mass function (MF) slopes, derived from G…
