2D solar modeling
P. Ventura, V. Penza, L. Li +3
Understanding the reasons of the cyclic variation of the total solar irradiance is one of the most challenging targets of modern astrophysics. These studies prove to be essential a…

The influence of the C+N+O abundances on the determination of the relative ages of Globular Clusters: the case of NGC 1851 and NGC 6121 (M4)
F. D'Antona, P. B. Stetson, P. Ventura +3
The color magnitude diagram (CMD) of NGC 1851 presents two subgiant branches (SGB), probably due the presence of two populations differing in total CNO content. We test the idea th…

The C+N+O abundances and the splitting of the subgiant branch in the Globular Cluster NGC 1851
P. Ventura, V. Caloi, F. D'Antona +3
Among the newly discovered features of multiple stellar populations in Globular Clusters, the cluster NGC 1851 harbours a double subgiant branch, that can be explained in terms of…
