The study of globular cluster evolution has many aspects yet to be fully understood. One of them is the coupling between the dynamical properties and the physical evolution of the stellar populations forming a single cluster. Here I will present a new model to explain both the anomalous extension and the large number of stars populating the blue hook locus in Omega Centauri. The key ingredients in this new explanation is the connection between the early dynamical properties of the second generation stars and their rotational velocity.

Abstract
The study of globular cluster evolution has many aspects yet to be fully understood. One of them is the coupling between the dynamical properties and the physical evolution of the stellar populations forming a single cluster. Here I will present a new model to explain both the anomalous extension and the large number of stars populating the blue hook locus in Omega Centauri. The key ingredients in this new explanation is the connection between the early dynamical properties of the second generation stars and their rotational velocity.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
