Exploration of morphological coherence in open clusters with a "core-shell'' structure
Qingshun Hu, Yu Zhang, Songmei Qin +3
The study of their morphological coherence allows us to obtain a better understanding of the morphological evolution of open clusters. We employed the ellipsoid fitting method to d…

Deciphering Star Cluster Evolution by Shape Morphology
Qingshun Hu, Yu Zhang, Ali Esamdin +2
We analyze the morphological evolution of open clusters and provide shape parameters for 265 open clusters. The results show that the overall shape of sample clusters becomes more…
