After the Big Bang, production of heavy elements in the early Universe takes place starting
from the formation of the first stars, their evolution, and explosion. The first supernova …

Nucleosynthesis in the s process takes place in the He-burning layers of low-mass
asymptotic giant branch (AGB) stars and during the He-and C-burning phases of massive …

To reach a deeper understanding of the origin of elements in the periodic table, we construct
Galactic chemical evolution (GCE) models for all stable elements from C (A= 12) to U (A …

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 …

An updated grid of stellar yields for low-to intermediate-mass thermally pulsing asymptotic
giant branch (AGB) stars is presented. The models cover a range in metallicity Z= 0.02 …

By using updated stellar low-mass stars models, we systematically investigate the
nucleosynthesis processes occurring in asymptotic giant branch (AGB) stars. In this paper …

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 …

Carbon-enhanced metal-poor (CEMP) stars in the Galactic Halo display enrichments in
heavy elements associated with either the s (slow) or the r (rapid) neutron-capture process …

Understanding the origin of the elements has been a decades-long pursuit, with many open
questions remaining. Old stars found in the Milky Way and its dwarf satellite galaxies can …

We explore the final fates of massive intermediate-mass stars by computing detailed stellar
models from the zero-age main sequence until near the end of the thermally pulsing phase …
