Reddening distribution across the center of the globular cluster Omega Centauri

A. Calamida, P. B. Stetson, G. Bono +17

We present new medium-band uvby Stromgren and broad-band VI photometry for the central regions of the globular cluster Omega Cen. From this photometry we have obtained differential…

The Carina dSph galaxy: where is the edge?

G. Bono, M. Monelli, A. R. Walker +13

Recent cosmological N-body simulations suggest that current empirical estimates of tidal radii in dSphs might be underestimated by at least one order of magnitude. To constrain the…

On the Horizontal Branch of the Galactic Globular NGC2808

V. Castellani, G. Iannicola, G. Bono +3

We present new UV (F218W) data for stars in the central region of the Galactic globular cluster NGC2808, collected with the WFPC2 camera on board of the Hubble Space Telescope. The…

On the anomalous red giant branch of the globular cluster Omega Cen

L. M. Freyhammer, M. Monelli, G. Bono +17

We present three different optical and near-infrared (NIR) data sets for evolved stars in the Galactic Globular Cluster Omega Cen The comparison between observations and homogeneou…
