Na-O anticorrelation and HB. IX. Kinematics of the program clusters. A link between systemic rotation and HB morphology?
M. Bellazzini, A. Bragaglia, E. Carretta +4
We use accurate radial velocities for 1981 member stars in 20 Galactic globular clusters, collected within our large survey aimed at the analysis of the Na-O anti-correlation, to s…
A Stromgren view of the multiple populations in globular clusters
Eugenio Carretta, Angela Bragaglia, Raffaele Gratton +2
We discuss a variety of photometric indices assembled from the uvby Stromgren system. Our aim is to examine the pros and cons of the various indices to find the most suitable one(s…
Chemical enrichment mechanisms in Omega Centauri: clues from neutron-capture elements
Valentina D'Orazi, Raffaele Gratton, Elena Pancino +4
In the complex picture of multiple stellar populations in globular clusters (GCs), a special role is played by NGC 5139 Omega Centauri. At variance with the majority of GCs, Omega…
