▪ Abstract Meteorites and interplanetary dust particles contain presolar stardust grains: solid
samples of stars that can be studied in the laboratory. The stellar origin of the grains is …

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 …

Extraterrestrial materials, including meteorites, interplanetary dust, and spacecraft-returned
asteroidal and cometary samples, provide a record of the starting materials and early …

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

In this paper we follow the Galactic enrichment of three easily observed light n-capture
elements: Sr, Y, and Zr. Input stellar yields have been first separated into their respective …

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 review the observed properties of extremely hot, hydrogen‐deficient post–asymptotic
giant branch (AGB) stars of spectral type [WC] and PG1159. Their H deficiency is probably …

We explore the variation in single-star 15–30${M} _ {\odot} $, nonrotating, solar metallicity,
pre-supernova MESA models that is due to changes in the number of isotopes in a fully …

We study the slow neutron capture process (s-process) in asymptotic giant branch (AGB)
stars using three different stellar evolutionary models computed for a 3 M☉, solar metallicity …

We report the discovery of five SiC grains and one graphite grain isolated from the
Murchison carbonaceous meteorite whose major-element isotopic compositions indicate an …
