Multiple stellar populations in Galactic globular clusters: observational evidence
Antonino P. Milone, Giampaolo Piotto, Luigi R. Bedin +3
An increasing number of both photometric and spectroscopic observations over the last years have shown the existence of distinct sub-populations in many Galactic globular clusters…
Ba stars and other binaries in first and second generation stars in globular clusters
Valentina D'Orazi, Raffaele Gratton, Sara Lucatello +3
The determination of the Ba abundance in globular cluster (GC) stars is a very powerful test to address several issues in the framework of multiple population scenarios. We measure…
Lithium abundances in red giants of M4: evidence for asymptotic giant branch star pollution in globular clusters?
Valentina D'Orazi, Anna F. Marino
The determination of Li and proton-capture element abundances in globular cluster (GC) giants allows us to constrain several key questions on the multiple population scenarios in G…
