Intrinsic iron abundance spreads in globular clusters
J. Schiappacasse-Ulloa, S. Lucatello, L. Magrini +2
Globular Clusters (GCs) host multiple stellar populations, likely composed of a subset of FG stars that enriched the intracluster medium and gave rise to SG stars, each characteris…
MUSE spectroscopic observations of the Young Massive Cluster NGC1850
A. Sollima, V. D'Orazi, R. Gratton +4
NGC1850 is the nearest Young Massive Cluster of the Local Group with a mass similar to those of Galactic globular clusters. Recent studies have revealed an extended morphology of i…
Stellar Population Astrophysics (SPA) with TNG. The old open clusters Collinder 350, Gulliver 51, NGC 7044, and Ruprecht 171
G. Casali, L. Magrini, A. Frasca +9
In the framework of the Stellar Population Astrophysics (SPA) project, we present new observations and spectral analysis of four sparsely studied open clusters, namely Collinder 35…
Chemical characterization of the globular cluster NGC 5634 associated to the Sagittarius dwarf spheroidal galaxy
Eugenio Carretta, Angela Bragaglia, Sara Lucatello +5
As part of our on-going project on the homogeneous chemical characterization of multiple stellar populations in globular clusters (GCs), we studied NGC 5634, associated to the Sagi…
The incidence of binaries in Globular Cluster stellar populations
S. Lucatello, A. Sollima, R. Gratton +4
Binary fraction and orbital characteristics provide indications on the conditions of star formation, as they shed light on the environment they were born in. Multiple systems are m…
Photometric and spectroscopic study of the intermediate-age open cluster NGC 2355
P. Donati, A. Bragaglia, E. Carretta +4
In this paper we analyse the evolutionary status and properties of the old open cluster NGC 2355, located in the Galactic anticentre direction, as a part of the long term programme…
