Dynamical age differences among coeval star clusters as revealed by blue stragglers
F. R. Ferraro, B. Lanzoni, E. Dalessandro +11
Globular star clusters that formed at the same cosmic time may have evolved rather differently from a dynamical point of view (because that evolution depends on the internal enviro…
High resolution reddening map in the direction of the stellar system Terzan 5
Davide Massari, Alessio Mucciarelli, Emanuele Dalessandro +7
We have used optical images acquired with the Hubble Space Telescope to construct the first high-resolution extinction map in the direction of Terzan 5, a peculiar stellar system i…
The central Blue Straggler population in four outer-halo globular clusters
Giacomo Beccari, Nora Lützgendorf, Christoph Olczak +6
Using HST/WFPC2 data, we have performed a comparative study of the Blue Straggler Star (BSS) populations in the central regions of the globular clusters AM 1, Eridanus, Palomar 3,…
A wide-area view of the Phoenix dwarf galaxy from VLT/FORS imaging
Giuseppina Battaglia, Marina Rejkuba, Eline Tolstoy +2
We present results from a wide-area photometric survey of the Phoenix dwarf galaxy, one of the rare dwarf irregular/ dwarf spheroidal transition type galaxies (dTs) of the Local Gr…
Star Formation in the Starburst Cluster in NGC 3603
Matteo Correnti, Francesco Paresce, Rossella Aversa +7
We have used new, deep, visible and near infrared observations of the compact starburst cluster in the giant HII region NGC 3603 and its surroundings with the WFC3 on HST and HAWK-…
UV Properties of Galactic Globular Clusters with GALEX I. The Color-Magnitude Diagrams
Ricardo P. Schiavon, Emanuele Dalessandro, Sangmo T. Sohn +10
We present GALEX data for 44 Galactic globular clusters obtained during 3 GALEX observing cycles between 2004 and 2008. This is the largest homogeneous data set on the UV photometr…
The BSS population in NGC 6229
N. Sanna, E. Dalessandro, B. Lanzoni +3
We have used a combination of high-resolution Hubble Space Telescope WFPC2 and wide-field ground-based observations in ultraviolet and optical bands to study the blue straggler sta…
