Observing early stellar nucleosynthesis

Nature Astronomy, 2021
A 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.

Nucleosynthesis and Stellar Evolution

Astrophysics and Space Science, 2002
Two of the basic building blocks of galaxies are stars and the interstellar medium. The evolution of the abundance composition in the latter and especially the enrichment of heavy elements as a function of space and time reflects in turn the history of star formation and the lifetimes of the diverse contributing stellar objects.

Stellar nucleosynthesis and galactic abundances

AIP Conference Proceedings, 2001
Galactic 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.

Reaction rates, nucleosynthesis, and stellar structure

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2007
Experimental 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 ...

The s-process of stellar nucleosynthesis

Progress in Particle and Nuclear Physics, 1986
Abstract 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.

Nucleosynthesis, Mass Loss and Stellar Evolution

1969
Stars 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).
