What is a globular cluster? An observational perspective
Raffaele Gratton, Angela Bragaglia, Eugenio Carretta +3
Globular clusters are large and dense agglomerate of stars. At variance with smaller clusters of stars, they exhibit signs of some chemical evolution. At least for this reason, the…
Stellar population astrophysics (SPA) with the TNG. Characterization of the young open cluster ASCC 123
A. Frasca, J. Alonso-Santiago, G. Catanzaro +10
Star clusters are key to understand the stellar and Galactic evolution. ASCC 123 is a little-studied, nearby and very sparse open cluster. We performed the first high-resolution sp…
NGC 6388 reloaded: some like it hot, but not too much
Eugenio Carretta, Angela Bragaglia
Multiple stellar populations in globular clusters (GCs) are defined and recognized by their chemical signature, with second generation stars showing the effects of nucleosynthesis…
Empirical estimates of the Na-O anti-correlation in 95 Galactic globular clusters
Eugenio Carretta
Large star-to-star abundance variations are direct evidence of multiple stellar populations in Galactic globular clusters (GCs). The main and most widespread chemical signature is…
