▪ Abstract We discuss the importance of very metal-poor stars to develop an understanding
of the nature of the first stars that formed in the Universe and the nucleosynthesis events …

▪ Abstract Abundance variations within globular clusters (GCs), and of GC stars with respect
to field stars, are important diagnostics of a variety of physical phenomena, related to the …

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 review recent determinations of the present‐day mass function (PDMF) and initial mass
function (IMF) in various components of the Galaxy—disk, spheroid, young, and globular …

Recent years have shown steady progress towards molecular electronics,, in which
molecules form basic components such as switches,,, diodes and electronic mixers. Often, a …

▪ 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 …

It has been proposed theoretically that the first generation of stars in the Universe
(population III) would be as massive as 100 solar masses (100 M⊙), because of inefficient …

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 …

We compile spectroscopic abundance data from 84 literature sources for 50 elements
across 3058 stars in the solar neighborhood, within 150 pc of the Sun, to produce the …

The chemical composition of the most metal-deficient stars largely reflects the composition of
the gas from which they formed. These old stars provide crucial clues to the star formation …
