Key Reactions in Nuclear Astrophysics

The workshop intends to discuss existing results in nuclear astrophysics and to identify key reactions for which the stable and RIB facilities need to assess information of interest for nuclear astrophysics. Physicists working on stellar modeling and observations (astronomy, cosmochemistry …) together with theoreticians and experimentalists working on nuclear reactions will meet with the purpose of identifying stellar scenarios needing nuclear reaction data that make sizable difference in stellar evolution and the optimal methods to obtain them.
