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…
Infrared observations of the candidate double neutron star system PSR J1811-1736
R. P. Mignani, A. Corongiu, C. Pallanca +1
PSR J1811-1736 (P=104 ms) is an old (~1.89 Gyrs) binary pulsar (P_orb=18.8 d) in a highly eccentric orbit (e=0.828) with an unidentified companion. Interestingly enough, the pulsar…
The Horizontal Branch in the UV Colour Magnitude Diagrams. II. The case of M3, M13 and M79
Emanuele Dalessandro, Maurizio Salaris, Francesco R. Ferraro +2
We present a detailed comparison between far-UV/optical colour Magnitude Diagrams obtained with high-resolution Hubble Space Telescope data and suitable theoretical models for thre…
Tagging the Chemical Evolution History of the Large Magellanic Cloud Disk
Emilio Lapenna, Alessio Mucciarelli, Livia Origlia +1
We have used high-resolution spectra obtained with the multifiber facility FLAMES at the Very Large Telescope of the European Southern Observatory to derive kinematic properties an…
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…
UV Properties of Galactic Globular Clusters with GALEX II. Integrated colors
Emanuele Dalessandro, Ricardo P. Schiavon, Robert T. Rood +4
We present ultraviolet (UV) integrated colors of 44 Galactic globular clusters (GGCs) observed with the Galaxy Evolution Explorer (GALEX) in both FUV and NUV bands. This data-base…
