The Hubble Space Telescope UV Legacy Survey of Galactic Globular Clusters. V. Constraints on Formation Scenarios
A. Renzini, F. D'Antona, S. Cassisi +16
We build on the evidence provided by our Legacy Survey of Galactic globular clusters (GC) to submit to a crucial test four scenarios currently entertained for the formation of mult…
The Hubble Space Telescope UV Legacy Survey of galactic globular clusters. VI. The internal kinematics of the multiple stellar populations in NGC 2808
A. Bellini, E. Vesperini, G. Piotto +9
Numerous observational studies have revealed the ubiquitous presence of multiple stellar populations in globular clusters and cast many hard challenges for the study of the formati…
Proper motions in Terzan 5: membership of the multi-iron sub-populations and first constrain to the orbit
Davide Massari, E. Dalessandro, F. R. Ferraro +6
By exploiting two sets of high-resolution images obtained with HST ACS/WFC over a baseline of ~10 years we have measured relative proper motions of ~70,000 stars in the stellar sys…
