On the effect of helium enhancement on bolometric corrections and Teff-colour relations
L. Girardi, F. Castelli, G. Bertelli +1
We evaluate the effects that variations in He content have on bolometric corrections and Teff-colour relations. To this aim, we compute ATLAS9 model atmospheres and spectral energy…

Clues on the evolution of the Carina dwarf spheroidal galaxy from the color distribution of its red giant stars
L. Rizzi, E. V. Held, G. Bertelli +1
The thin red giant branch (RGB) of the Carina dwarf spheroidal galaxy appears at first sight quite puzzling and seemingly in contrast with the presence of several distinct bursts o…

Testing intermediate-age stellar evolution models with VLT photometry of LMC clusters. III. Padova results
G. Bertelli, E. Nasi, L. Girardi +3
The color-magnitude diagrams (CMDs) of three intermediate-age LMC clusters, NGC 2173, SL556 and NGC2155 are analyzed to determine their age and metallicity basing on Padova stellar…
