Properties of second generation stars in Globular Clusters
Eugenio Carretta, Angela Bragaglia, Raffaele G. Gratton +1
We present the first results from the analysis of GIRAFFE spectra of more than 1200 red giants stars in 19 Galactic Globular Clusters (GCs), to study the chemical composition of se…
Open clusters as key tracers of Galactic chemical evolution. III. Element abundances in Berkeley 20, Berkeley 29, Collinder 261, and Melotte 66
P. Sestito, A. Bragaglia, S. Randich +3
Galactic open clusters are since long recognized as one of the best tools for investigating the radial distribution of iron and other metals. We employed FLAMES at VLT to collect U…
Disentangling the Galaxy at low Galactic latitudes
M. Cignoni, M. Tosi, A. Bragaglia +2
We have used the field stars from the open cluster survey BOCCE, to study three low-latitude fields imaged with the Canada-France-Hawaii telescope (CFHT), with the aim of better un…
The Bologna Open Clusters Chemical Evolution project (in short: BOCCE)
Angela Bragaglia
I present here our project, the Bologna Open Clusters Chemical Evolution (BOCCE) project, aimed at using Open Clusters as tracers of the disk properties and their evolution with ti…
The link between chemical anomalies along the red giant branch and the horizontal branch extension in globular clusters
Eugenio Carretta, Alejandra Recio-Blanco, Raffaele G. Gratton +2
We find a strong correlation between the extension of the Na-O anticorrelation observed in red giant branch (RGB) stars and the high temperature extension of the horizontal branch…
The chemical abundance of the very metal rich old Open Clusters NGC 6253 and NGC 6791
Eugenio Carretta, Angela Bragaglia, Raffaele Gratton
In the framework of a project aiming at deriving in a homogeneous way the properties (age, distance, reddening and detailed chemical abundances) of a large sample of old open clust…
