Multi-wavelength observations of stellar populations in Galactic globular clusters
F. R. Ferraro
I report on some recent results in the framework of a complex project aimed to characterize the photometric properties of stellar populations in Galactic Globular Clusters.
Photometric properties of Stellar Populations in GGCs: a multi-wavelength approach
Francesco R. Ferraro
Globular star clusters are extremely important astrophysical objects since (1) they are prime laboratories for testing stellar evolution; (2) they are ``fossils'' from the epoch of…
Binary stars in globular clusters: detection of a binary sequence in NGC 2808?
F. R. Ferraro, E. Carretta, F. Fusi Pecci +1
A CCD V,V-I colour-magnitude diagram (CMD) of the Galactic globular cluster NGC 2808 has been obtained with the ESO-NTT, reaching down to V ~ 24. The highly populated Main Sequence…
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 stellar population of the Globular Cluster M 3. II: CCD photometry of additional 10,000 stars
F. R. Ferraro, E. Carretta, C. E. Corsi +5
We present BVI CCD photometry for more than 10,000 stars in the innermost region (0.3' < r <~ 4') of the globular cluster M 3. When added to the previous photographic photometry by…
