The Gaia-ESO Survey: Kinematics of seven Galactic globular clusters
C. Lardo, E. Pancino, M. Bellazzini +24
The Gaia-ESO survey is a large public spectroscopic survey aimed at investigating the origin and formation history of our Galaxy by collecting spectroscopy of representative sample…
Chemical enrichment in very low-metallicity environments: Bootes I
Donatella Romano, Michele Bellazzini, Else Starkenburg +1
We present different chemical evolution models for the ultrafaint dwarf galaxy Bootes I. We either assume that the galaxy accretes its mass through smooth infall of gas of primordi…
Kinematics of a globular cluster with an extended profile: NGC5694
M. Bellazzini, A. Mucciarelli, A. Sollima +6
We present a study of the kinematics of the remote globular cluster NGC5694 based on GIRAFFE@VLT medium resolution spectra. A sample of 165 individual stars selected to lie on the…
Ceci n'est pas a globular cluster: the metallicity distribution of the stellar system Terzan 5
Davide Massari, A. Mucciarelli, F. R. Ferraro +9
We present new determinations of the iron abundance for 220 stars belonging to the stellar system Terzan 5 in the Galactic bulge. The spectra have been acquired with FLAMES at the…
The extended structure of the dwarf irregular galaxy Sagittarius
G. Beccari, M. Bellazzini, F. Fraternali +6
We present a detailed study of the stellar and HI structure of the dwarf irregular galaxy Sagittarius. We use new deep and wide field photometry to trace the surface brightness pro…
First evidence of fully spatially mixed first and second generations in globular clusters: the case of NGC 6362
E. Dalessandro, D. Massari, M. Bellazzini +6
We present the first evidence of multiple populations in the Galactic globular cluster NGC 6362. We used optical and near-UV Hubble Space Telescope and ground based photometry, fin…
