We then take advantage of these new member lists to study the morphological properties and the mass segregation levels of the clusters. We revisit the membership lists of OCs from the solar vicinity, in particular, by extending these membership lists to the peripheral areas through Gaia EDR3. The Gaia catalog is very appropriate for finding members of OCs at large distance from their centers.Īims. The analysis of structural parameters of OCs as a function of their age and position in the Galaxy constrains theoretical models of cluster evolution. The distribution of member stars in the surroundings of an open cluster (OC) can shed light on the process of its formation, evolution, and dissolution.
