The Stellar Mass Distribution in the Giant Star Forming Region NGC 346
E. Sabbi, M. Sirianni, A. Nota +8
Deep F555W and F814W Hubble Space Telescope ACS images are the basis for a study of the present day mass function (PDMF) of NGC346, the largest active star forming region in the Sm…
The old open clusters Berkeley 32 and King 11
Monica Tosi, Angela Bragaglia, Michele Cignoni
We have obtained CCD BVI imaging of the old open clusters Berkeley 32 and King 11. Using the synthetic colour-magnitude diagram method with three different sets of stellar evolutio…
Very metal poor Classical Cepheids: variables in IZw18
G. Fiorentino, M. Marconi, G. Clementini +5
In the framework of an ongoing ACS@HST project (HST program #10586, PI: Aloisi) we have obtained deep multi-color imaging of the very metal-poor Blue Compact Dwarf galaxy IZw18. Th…
The chemical evolution of Omega Centauri's progenitor system
D. Romano, F. Matteucci, M. Tosi +5
Chemical evolution models are presented for the anomalous globular cluster Omega Centauri. After demonstrating that the chemical features of Omega Cen can not be reproduced in the…
Star formation histories of resolved stellar populations: in and beyond the Local Group
Monica Tosi
The exploitation of the power and the spatial resolution of HST and new generation ground-based telescopes allows to measure with good precision the individual stars of galaxies in…
AGB stars and the chemical evolution of galaxies
Monica Tosi
Asymptotic Giant Branch (AGB) stars are important players in the chemical evolution modelling of galaxies, because they are major producers of several chemical elements and excelle…
