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…
Near-Infrared photometry of LMC cluster Reticulum
M. Dall'Ora, G. Bono, J. Storm +11
We present near-infrared (JKs) time series data of the Large Magellanic Cloud (LMC) cluster Reticulum. The observing strategy and data reduction (DAOPHOTII/ALLFRAME) allowed us to…
NGC1866: New analysis from HST-WFPC2 observations of the inner regions
E. Di Carlo, G. Raimondo, E. Brocato +2
We report new results on the LMC globular cluster NGC 1866 obtained by analyzing F555W and F814W images from WFPC2@HST. On the basis of the CMD we derive information on the cluster…
Modern Stellar Evolution Models for Low Mass Stars
V. Castellani
The status of the art for evolutionary models of low mass, population II stars is revisited, stressing the need for the models to be preliminarily tested with suitable observationa…
Some clues on the tilt of the Horizontal Branches in metal-rich clusters
G. Raimondo, V. Castellani, S. Cassisi +2
We discuss some clues on the large tilt observed in the Horizontal Branch of the metal-rich galactic globular clusters NGC 6388 and NGC 6441. This not yet understood feature is inv…
The tricky galactic cluster NGC2420
P. G. Prada Moroni, V. Castellani, S. Degl'Innocenti +1
We discuss the CM diagram of the galactic cluster NGC2420 to the light of current theoretical predictions. By relying on the most recent updating of the physical input, one finds t…
