Star Counts in the Globular Cluster Omega Centauri. I. Bright Stellar Components
V. Castellani, A. Calamida, G. Bono +8
We present an extensive photometry on HB, RGB, and MSTO stars in Omega Cen. The central regions of the cluster were covered with a mosaic of F435W, F625W, and F658N-band data colle…
Hot Flashers and He Dwarfs in Galactic Globulars
M. Castellani, V. Castellani, P. G. Prada Moroni
We revisit the evolutionary scenario for Hot Flasher low-mass structures, where mass loss delays the He flash till the initial phases of their White Dwarf cooling sequence. Our aim…
B, V, I photometry of the complete sample of 23 Cepheids in the field of NGC 1866
I. Musella, V. Ripepi, E. Brocato +8
We present the result of BVI photometry, obtained by using FORS@VLT, of the Cepheids present in the field of the Large Magellanic Cloud cluster NGC 1866. We found the 22 known vari…
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…
RR Lyrae variables in Galactic globular clusters V. The case of M3 pulsators
M. Castellani, V. Castellani, S. Cassisi
We use our synthetic Horizontal Branch (HB) procedure to approach the debated problem concerning the adequacy of canonical HB stellar models to account for the observed peaked dist…
