Massive Star Modeling and Nucleosynthesis

Frontiers in Astronomy and Space Sciences, 2021
After a brief introduction to stellar modeling, the main lines of massive star evolution are reviewed, with a focus on the nuclear reactions from which the star gets the needed energy to counterbalance its gravity.

Proton-rich nucleosynthesis and nuclear physics [PDF]

, 2012
Although the detailed conditions for explosive nucleosynthesis are derived from astrophysical modeling, nuclear physics determines fundamental patterns in abundance yields, not only for equilibrium processes. Focussing on the nu p- and the gamma-process,

Neutron-Driven Nucleosynthesis in Stellar Plasma

Frontiers in Physics, 2022
A large uncertainty for the slow neutron capture nucleosynthesis (s-process) models is caused by the amount of neutrons available to the process itself.

Design study of a HPGe detector array for β-decay investigation in laboratory ECR plasmas

Frontiers in Physics, 2022
In the frame of the PANDORA project, a new experimental approach aims at measuring in-plasma β-decay rate as a function of thermodynamical conditions of the environment, namely a laboratory magnetized plasma able to mimic some stellar-like conditions ...

Isomers in the Cosmos

Atoms, 2023
The nucleosynthesis of chemical elements has been established to be the result of a variety of different types of nuclear reactions in stars. Under the extreme temperatures and densities encountered in such environments, nuclear isomers can be populated ...

Primordial Nucleosynthesis: Theory and Observations [PDF]

, 1999
We review the Cosmology and Physics underlying Primordial Nucleosynthesis and survey current observational data in order to compare the predictions of Big Bang Nucleosynthesis with the inferred primordial abundances. From this comparison we report on the
