THE ROLE OF NUCLEAR PHYSICS IN PROVIDING DATA FOR ASTROPHYSICS — •Stephane Goriely — IAA - Universite Libre de Bruxelles, CP 226, Campus de la Plaine, B-1050 Brussels

Impressive progress has been made for the last decades in the various fields related to nuclear astrophysics. However, major problems and puzzles remain, which challenges continuously the nuclear astrophysics concepts and findings. To put them on a safer footing requires a deeper and more precise understanding of the many nuclear physics processes operating in the astrophysical environment.

More specifically, major difficulties related to the specific conditions of the astrophysical plasma remain (capture of charged particles at low energies, large number of nuclei and properties to consider, exotic species, high-temperature and/or high-density environments, ...). In many astrophysical scenarios, only theoretical predictions can fill the gaps. The nuclear ingredients to the reaction or weak interaction models should preferentially be estimated from microscopic global predictions based on sound and reliable nuclear models which, in turn, can compete with more phenomenological highly-parametrized models in the reproduction of experimental data. The latest developments made in deriving the nuclear inputs of relevance in astrophysics applications are reviewed. Emphasis is made on the possibility to make use of reliable microscopic models for practical applications.
