Synthetic Stellar Clusters for Pop III
G. Raimondo, E. Brocato, S. Cassisi +1
We present preliminary results of an incoming theoretical work concerning the integrated properties of the Population III clusters of stars. On the basis of synthetic Color-Magnitu…
A new investigation on the Antlia Dwarf Galaxy
A. M. Piersimoni, G. Bono, M. Castellani +4
We present deep (I,V-I) and (I,B-I) color-magnitude diagrams (CMDs) of the Antlia dwarf galaxy, based on Science Verification (SV) data collected with the FORS I camera on the ESO…
Nonradial modes in RR Lyrae stars
W. A. Dziembowski, S. Cassisi
We present a survey of nonradial mode properties in evolutionary sequences of RR Lyrae star models. Attention is focused on the modes that may be driven by the opacity mechanism an…
On the very long term evolutionary behavior of hydrogen-accreting Low-Mass CO white dwarfs
L. Piersanti, S. Cassisi, I. Iben +1
Hydrogen-rich matter has been added to a CO white dwarf of initial mass 0.516 \msun at the rates and \msun \yrm1, and results are compared with those fo…
The Initial Mass Function of the Galactic Bulge Down to ~0.15 Msun
M. Zoccali, S. Cassisi, J. A. Frogel +5
We present a luminosity function (LF) for lower main sequence stars in the Galactic bulge near (l,b)=(0,-6) to J=24, corresponding to M_J~9.3. This LF is derived from HST + NICMOS…
Comparison between predicted and empirical DV(Bump -HB) in Galactic Globular Clusters
M. Zoccali, S. Cassisi, G. Piotto +2
We present observational estimates of DV(Bump-HB) in a sample of 28 Galactic Globular Clusters (GGCs) observed by HST. The photometric accuracy and the sizable number of stars meas…
