Abstract: The reaction 22Ne(𝛼,𝑛)25Mg is one of the main neutron source in stars, providing the neutron flux for the weak component of the s-process in massive stars and partially contributing to the main component in AGB stars. For these reasons, its reaction rate is crucial in nuclear astrophysics.

However, the limited availability of experimental data in the energy range of astrophysical interest still leads to significant uncertainties in the reaction rate and in nucleosynthesis predictions.

Abstract: Nuclear clustering is a phenomenon where the structure of the nucleus tends towards clumps of alpha particles rather than a homogenous ball of protons and neutrons. Understanding this feature of the nuclear force is particularly important for astrophysics, for instance in the Hoyle state which is essential to the triple-alpha process.

Note that this seminar will take place at 9am Eastern Time / 3 pm CET and Daylight Savings Time has ended in the US.

Abstract: Stars are the element factories of the universe. Stellar explosions distribute freshly synthesized radionuclides in the interstellar medium and lead to the chemical enrichment of galaxies. These cataclysmic events moreover shape the interstellar medium and form large scale structures in the universe.

Abstract: The production of elements produced in stars is one of the main questions that is of critical interest in nuclear astrophysics. The majority of elements are traditionally produced via the slow (s) and rapid (r) processes.

Abstract: Nuclear reactions among charged particles in stars take place at energies generally well below the Coulomb barrier, so the Coulomb barrier penetration factor exponentially suppresses the cross sections down to values as small as few nanobarns or picobarns. Therefore, approaching astrophysical energies opens new challenges and calls for new approaches.
