The role of cluster mass in the multiple populations of Galactic and extragalactic globular clusters
Edoardo P. Lagioia, Antonino P. Milone, Anna F. Marino +2
Studies based on Hubble Space Telescope () photometry in F275W, F336W, and F438W have shown that the incidence and complexity of multiple populations (MPs) in Globular Cluster…
The SkyMapper DR1.1 Search for Extremely Metal-Poor Stars
G. S. Da Costa, M. S. Bessell, A. D. Mackey +10
We present and discuss the results of a search for extremely metal-poor stars based on photometry from data release DR1.1 of the SkyMapper imaging survey of the southern sky. In pa…
Mass loss of different stellar populations in globular clusters
Marco Tailo
Once fixed the age and metallicity; the colour distribution of horizontal branch stars in a globular cluster depends on few parameters: the helium abundance of the population and t…
Multiple stellar populations: from old Milky Way globulars to young star clusters
Anna F. Marino
I present the latest results from our group about the multiple stellar populations in the old Milky Way globular clusters (GCs) and in the young systems both in the Magellanic Clou…
Helium variations in Galactic and extragalactic Globular Clusters
E. P. Lagioia, A. Milone, A. Marino +3
The recent measurements of internal variations of helium in Galactic and extragalactic Globular Clusters (GCs) set binding constraints to the models of formation of Multiple Popula…
Kinematics of Multiple Stellar Populations in Globular Clusters with Gaia
Giacomo Cordoni, Antonino P. Milone, Alessandra Mastrobuono-Battisti +3
The internal dynamics of multiple stellar populations in Globular Clusters (GCs) provides unique constraints on the physical processes responsible for their formation. Specifically…
