Nature and nurture: the dynamical ages of in situ and accreted globular clusters in the Milky Way
Eugenio Carretta
The bifurcated age-metallicity relation of globular clusters (GCs) in the Milky Way (MW) shows that GCs are either originated in situ or accreted into the Galaxy from former satell…

Inconsistent metallicity spreads in first generation stars of globular clusters from high resolution spectroscopy and HST photometry
Eugenio Carretta, Angela Bragaglia
An open issue about multiple stellar populations in globular clusters (GCs) is the possible existence of metallicity spreads in first generation (FG) stars. Recent estimates based…

A comparison of abundance analyses of first generation stars in multiple populations in 47 Tuc and NGC 3201
Eugenio Carretta, Angela Bragaglia
The distinction of the stellar content in globular clusters (GCs) in multiple stellar populations characterized by different amounts of proton-capture elements has been well assess…
