Discovery of another peculiar radial distribution of Blue Stragglers in Globular Clusters: The case of 47 Tuc
Francesco R. Ferraro, Giacomo Beccari, Robert T. Rood +3
We have used high resolution WFPC2-HST and wide field ground-based observations to construct a catalog of blue straggler stars (BSS) in the globular cluster 47 Tuc spanning the ent…
Tracing the Sgr Stream with 2MASS. Detection of Stream stars around Outer Halo Globular Clusters
M. Bellazzini, R. Ibata, F. R. Ferraro +1
We use infrared Color Magnitude Diagrams from the 2-Micron All-Sky Survey (2MASS) to search for stars belonging to the tidal stream of the Sagittarius dwarf spheroidal galaxy (Sgr…
M75, a Globular Cluster with a Trimodal Horizontal Branch. II. BV Photometry of the RR Lyrae Variables
T. M. Corwin, M. Catelan, H. A. Smith +3
We present new BV CCD photometry, light curves, and ephemerides for 9 previously known, 29 newly detected RR Lyrae variables and one newly detected variable of an unknown type in t…
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.
