Stellar Evolution and Nucleosynthesis
Journal of Plasma and Fusion Research, 2003 Here we address the phases of stellar evolution and nucleosynthesis which are more important in connection to chemical enrichment and galactic chemical evolution. In the following one should keep in mind that the stellar evolution results are influenced by the physics adopted in the models.

Observing early stellar nucleosynthesis
Nature Astronomy, 2021A fluorine abundance measurement in a high-redshift galaxy demonstrates an early, quick rise in chemical enrichment of the Universe. The presence of fluorine at this early epoch also reveals a unique early source of the element.

Stellar nucleosynthesis and galactic abundances
AIP Conference Proceedings, 2001Galactic abundances are neither constant in time nor do they evolve in a simple fashion, e.g., by an enrichment of heavy elements in constant relative proportions. Instead, their evolution in space and time reflects the history of star formation and the lifetimes of the diverse contributing stellar objects.

The s-process of stellar nucleosynthesis
Progress in Particle and Nuclear Physics, 1986Abstract The present status of our understanding of the s process of stellar nucleosynthesis is reviewed from the point of view of nuclear physics. Observed abundances of chemical elements and their isotopes are combined with information on neutron capture cross sections and nuclear structure.

Stellar Nucleosynthesis and Chemical Evolution of Galaxies
EAS Publications Series, 2007We present the basic theory of nuclear reactions in stars and sketch the general rules of stellar evolution. Then we shortly review the subject of supernova explosions both by core collapse in massive stars (type II) and carbon-deflagration in binary systems when one of the components is a White Dwarf accreting mass from the companion

Nuclear Aspects of Stellar and Explosive Nucleosynthesis
2002The majority of nuclear reactions in astrophysics involve unstable nuclei which are not yet fully accessible by experiments. Therefore, there is high demand for reliable predictions of cross sections and reaction rates by theoretical means. The majority of reactions can be treated in the framework of the statistical model (Hauser-Feshbach).

Reaction rates, nucleosynthesis, and stellar structure
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2007Experimental reaction rates are the necessary nuclear physics input for quantitative studies of nucleosynthesis during the hydrostatic phases of stellar evolution as well as in explosive scenarios such as novae, X-ray burster, or supernovae. Such studies represent crucial tests of the respective astrophysical models, which themselves constitute the ...

Nucleosynthesis, Mass Loss and Stellar Evolution
1969Stars are formed from material of the interstellar medium with a given composition: X (the fraction of hydrogen), Y (the fraction of helium), Z (the fraction of the sum of the heavy elements, which can be splitted in Z1, Z2, Z3,... representing these heavy elements).
