The pollution from massive AGB stars favoured by strong hot bottom burning
Paolo Ventura, Francesca D'Antona
Stars of intermediate mass (~4-8Msun) evolve to the stage of white dwarfs through the asymptotic giant branch (AGB) stage: stationary hydrogen shell burning and helium thermal puls…

Noble gases Neon and argon: a role for the chemical patterns of multiple populations in globular clusters?
P. Ventura, F. D'Antona, M. Tailo +3
We focus on the sodium destruction in models reaching the high hot bottom burning temperatures needed to efficiently cycle oxygen to nitrogen in AGB models at the nominal [Fe/H] of…

The stellar to sub-stellar masses transition in 47 Tuc
C. Ventura, M. Tailo, P. Ventura +4
Context: The study of the Globular Cluster 47 Tuc offers the opportunity to shed new light on the debated issue on the presence of multiple populations in Globular Clusters, as rec…
