Blue Straggler Stars: a direct comparison of Star counts and population ratios in six Galactic Globular Clusters
Francesco R. Ferraro, Alison Sills, Robert T. Rood +2
The central regions of six Galactic Globular Clusters (GGCs) (M3, M80, M10, M13, M92 and NGC 288) have been imaged using HST-WFPC2 and the ultraviolet (UV) filters (F255W, F336W).…
Blue Stragglers, Young White Dwarfs and UV-excess stars in the core of 47 Tuc
Francesco R. Ferraro, Nichi D'Amico, Andrea Possenti +2
We used a set of archived HST/WFPC2 images to probe the stellar population in the core of the nearby Galactic Globular Cluster (GGC) 47 Tuc. From the ultraviolet (UV) Color Magnitu…
VLT Observations of the Peculiar Globular Cluster NGC6712, III: The Evolved Stellar Population
Barbara Paltrinieri, Francesco R. Ferraro, Francesco Paresce +1
We present extensive UBVR photometry of the Galactic globular cluster (GGC) NGC6712 obtained with the ESO Very Large Telescope (VLT) which reach down to two magnitudes below the ma…
Very Large Telescope Observations of the peculiar globular cluster NGC6712. Discovery of a UV, H-alpha excess star in the core
Francesco R. Ferraro, Barbara Paltrinieri, Francesco Paresce +1
We present results from multi-band observations in the central region of the cluster NGC6712 with the ESO-Very Large Telescope. Using high resolution images we have identified thre…
Another Faint UV Object Associated with a Globular Cluster X-Ray Source: The Case of M92
Francesco R. Ferraro, Barbara Paltrinieri, Robert T. Rood +2
The core of the metal poor Galactic Globular Cluster M92 (NGC 6341) has been observed with WFPC2 on the Hubble Space Telescope through visual, blue and mid-UV filters in a program…
The Luminosity Function of M3
R. T. Rood, E. Carretta, B. Paltrinieri +6
We present a high precision, large sample luminosity function (LF) for the Galactic globular cluster M3. With a combination of ground based and Hubble Space Telescope data we cover…
