Super AGB and AGB evolution and the chemical inventory in NGC 2419
Paolo Ventura, Francesca D'Antona, Marcella Di Criscienzo +3
We follow the scenario of formation of second generation stars in globular clusters by matter processed by hot bottom burning (HBB) in massive asymptotic giant branch (AGB) stars a…
Models for the lithium abundances of multiple populations in globular clusters and the possible role of the Big Bang lithium
F. D'Antona, A. D'Ercole, R. Carini +2
Globular cluster stars show chemical abundance patterns typical of hot-CNO processing. Lithium is easily destroyed by proton capture in stellar environments, so its abundance may b…
Dust formation around AGB and SAGB stars: a trend with metallicity?
P. Ventura, M. Di Criscienzo, R. Schneider +6
We calculate the dust formed around AGB and SAGB stars of metallicity Z=0.008 by following the evolution of models with masses in the range 1M<M<8M throughthe thermal pulses phase,…
The role of super-asymptotic giant branch ejecta in the abundance patterns of multiple populations in globular clusters
Annibale D'Ercole, Francesca D'Antona, Roberta Carini +2
In order to account for the chemical composition of a stellar second generation (SG), Globular Clusters (GCs) evolution models based on the asymptotic giant branch (AGB) scenario s…
