Globular clusters are large and dense agglomerate of stars. At variance with smaller clusters
of stars, they exhibit signs of some chemical evolution. At least for this reason, they are …

▪ Abstract The current status of modeling the evolution and nucleosynthesis of asymptotic
giant branch (AGB) stars is reviewed. The principles of AGB evolution have been …

The chemical evolution of the Universe is governed by the chemical yields from stars, which
in turn are determined primarily by the initial stellar mass. Even stars as low as 0.9 M⊙ can …

We present new theoretical stellar yields and surface abundances for three grids of metal-
rich asymptotic giant branch (AGB) models. Post-processing nucleosynthesis results are …

We present abundances of Fe, Na, and O for 1409 red giant stars in 15 galactic globular
clusters (GCs), derived from the homogeneous analysis of high-resolution …

We present homogeneous abundance determinations for iron and some of the elements
involved in the proton-capture reactions (O, Na, Mg, Al, and Si) for 202 red giants in 17 …

Aims. We propose the Wind of Fast Rotating Massive Stars scenario to explain the origin of
the abundance anomalies observed in globular clusters. Methods. We compute and present …

Isotope ratios have opened a new window into the study of the details of stellar evolution,
supernovae and galactic chemical evolution. We present the evolution of the isotope ratios …

We present yields from stars of mass in the range M⊙≤ M≤ 8 M⊙ of metallicities Z= 3×
10− 4 and 8× 10− 3, thus encompassing the chemistry of low-and high-Z globular clusters …

We study the s-process abundances (A≳ 90) at the epoch of the solar system formation.
Asymptotic giant branch yields are computed with an updated neutron capture network and …
