Scaled solar tracks and isochrones in a large region of the Z-Y plane. II. From 2.5 to 20 solar masses
G. Bertelli, E. Nasi, L. Girardi +1
We extend our theoretical computations for low-mass stars to intermediate-mass and massive stars, for which few databases exist in the literature. Evolutionary tracks and isochrone…
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…
Theoretical isochrones in several photometric systems I. Johnson-Cousins-Glass, HST/WFPC2, HST/NICMOS, Washington, and ESO Imaging Survey filter sets
L. Girardi, G. Bertelli, A. Bressan +5
We provide tables of theoretical isochrones in several photometric systems. To this aim, the following steps are followed: (1) First, we re-write the formalism for converting synth…
On the galactic disc age-metallicity relation
G. Carraro, Y. K. Ng, L. Portinari
A comparison is made between the age-metallicity relation obtained from four different types of studies: F and G stars in the Solar Neighbourhood, analysis of open clusters, galact…
