HST UV Observations of the Cores of M3 and M13
Francesco R. Ferraro, Barbara Paltrinieri, Flavio Fusi Pecci +3
We present preliminary results from HST/WFPC2 observations of the central regions of the of the Galactic globular clusters M13 and M3. The clusters are almost identical in most res…
HST Observations of Blue Straggler Stars in the Core of the Globular Cluster M3
F. R. Ferraro, B. Paltrinieri, F. Fusi Pecci +7
The core of the Galactic Globular Cluster M3 (NGC 5272) has been observed with the WFPC2 through the filters F255W, F336W, F555W, and F814W. Using these observations along with a t…
The Far-Ultraviolet Radiation from Elliptical Galaxies
Ben Dorman
Since the discovery of the Ultraviolet Upturn Phenomenon (``UVX'') in early-type galaxies it has been clear that the stellar populations of such systems contain an unexpected hot c…
HST Observations of High-Density Globular Clusters
G. Piotto, C. Sosin, I. R. King +6
In this paper we present preliminary results from our HST project aimed at exploring the connection between the stellar dynamics and stellar evolution in the cores of high-density…
Globular Clusters Color-Magnitude Diagrams with HST
C. Sosin, G. Piotto, S. G. Djorgovski +6
In this paper we present the 13 B and V color-magnitude diagrams discussed by Piotto et al. in the same Procedings. The data have been collected with the WFPC2 camera on HST. We em…
