Trojan Horse Investigation for AGB Stellar Nucleosynthesis
Universe, 2022 Asymptotic Giant Branch (AGB) stars are among the most important astrophysical sites influencing the nucleosynthesis and the chemical abundances in the Universe. From a pure nuclear point of view, several processes take part during this peculiar stage of

Developing aluminum molecular plating for neutron-induced reaction target fabrication [PDF]
Scientific Reports$$^{26}$$ Al is an important radionuclide for research on stellar nucleosynthesis in the Galaxy and the environment of the early solar system. Computational simulations involving the production and destruction of $$^{26}$$ Al in stellar nucleosynthesis ...

Neutron captures in stellar nucleosynthesis [PDF]
EPJ Web of Conferences, 2023 Apart from cosmological hydrogen and helium, chemical elements in the Universe are produced in stars, during both quiescent and explosive phases. The Sun chemical distribution witnesses the pollution from already extinct stellar generations at different ...

Turbulence and nuclear reactions in 3D hydrodynamics simulations of massive stars [PDF]
EPJ Web of Conferences, 2023 Our knowledge of massive star evolution and nucleosynthesis is limited by uncertainties related to multi-dimensional processes taking place in stellar interiors.

The impact of n_TOF data on s-process modelling [PDF]
EPJ Web of Conferences, 2023 We show examples of the impact of the Maxwellian averaged capture cross sections determined at n_TOF over the past 20 years on AGB stellar nucleosynthesis models.

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.

Analysis of the impact of the 204Tl neutron capture cross section on the s-process only isotope 204Pb [PDF]
EPJ Web of Conferences, 2022 In the study of the slow (s) process of nucleosynthesis branching nuclei become of particular interest. These nuclei have half-lives of the order of 1-100 years, and in the stellar environment their decay rate can compete with the neutron capture rate ...

Impact of AGB Stars on the Chemical Evolution of Neutron-Capture Elements
Universe, 2022 In this review, we discuss the impact of s-process nucleosynthesis in asymptotic giant branch stars on the enrichment of heavy elements. We review the main steps made on this subject in the last 40 years and discuss the importance of modelling the ...
