On a new Near-Infrared method to estimate the absolute ages of star clusters: NGC3201 as a first test case
G. Bono, P. B. Stetson, D. A. VandenBerg +24
We present a new method to estimate the absolute ages of stellar systems. This method is based on the difference in magnitude between the main sequence turn-off (MSTO) and a well d…
Stromgren photometry of Galactic Globular Clusters. II Metallicity distribution of red giants in Omega Centauri
A. Calamida, G. Bono, P. B. Stetson +23
We present new intermediate-band Stroemgren photometry based on more than 300 u,v,b,y images of the Galactic globular cluster Omega Cen. Optical data were supplemented with new mul…
The Leo IV dwarf spheroidal galaxy: color-magnitude diagram and pulsating stars
M. I. Moretti, M. Dall'Ora, V. Ripepi +10
We present the first V, B-V color-magnitude diagram of the Leo IV dwarf spheroidal galaxy, a faint Milky Way satellite recently discovered by the Sloan Digital Sky Survey. We have…
On the radial distribution of horizontal branch stars in ngc2808
G. Iannicola, M. Monelli, G. Bono +17
We present accurate new ultraviolet and optical BVI photometry for the Galactic globular cluster ngc2808, based on both ground-based and archival HST imagery. From this we have sel…
Pulsating Variable Stars in the Coma Berenices dwarf spheroidal galaxy
I. Musella, V. Ripepi, G. Clementini +8
We present B, V, I time-series photometry of the Coma Berenices dwarf spheroidal galaxy, a faint Milky Way satellite, recently discovered by the Sloan Digital Sky Survey. We have o…
