Stellar Interpretation of Meteoritic Data and PLotting for Everyone (SIMPLE): Isotope Mixing Lines for Six Sets of Core-Collapse Supernova Models

Marco Pignatari, Mattias Ek, Georgy V. Makhatadze +15

Bulk meteorites and their inclusions exhibit, for many chemical elements, isotopic variability produced by nucleosynthetic events in stars and supernovae before the formation of th…

The NuGrid AGB Evolution and Nucleosynthesis Data Set

Umberto Battino, Marco Pignatari, Ashley Tattersall +2

Asymptotic Giant Branch (AGB) stars play a key role in the chemical evolution of galaxies. These stars are the fundamental stellar site for the production of light elements such as…

Impact of newly measured 26Al(n, p)26Mg and 26Al(n, α)23Na reaction rates on the nucleosynthesis of 26Al in stars

Umberto Battino, Claudia Lederer-Woods, Marco Pignatari +6

The cosmic production of the short-lived radioactive nuclide 26Al is crucial for our understanding of the evolution of stars and galaxies. However, simulations of the stellar sites…

3D Macro Physics and Light Odd-Z Element Production in O-C Shell Mergers: Implications for production and radiogenic heating inventories of rocky exoplanets

Joshua Issa, Falk Herwig, Stephen J. Mojzsis +1

The light odd-Z elements P, Cl, K, and Sc are underproduced in galactic chemical evolution models compared to spectroscopic observations of stars in the Milky Way. The most promisi…

Impact of 3D macro physics and nuclear physics on the p nuclei in O-C shell mergers

Joshua Issa, Falk Herwig, Pavel Denissenkov +1

O-C shell mergers in massive stars are a site for producing the p nuclei by the process, but 1D stellar models rely on mixing length theory, which does not match the radial ve…

Nuclear Physics Mid Term Plan at LNGS

R. Buompane, F. Cavanna, C. Curceanu +59

The Istituto Nazionale di Fisica Nucleare-Laboratori Nazionali del Gran Sasso (LNGS) is one of the largest underground physics laboratory, a very peculiar environment suited for ex…
