Seminar- Neutron Skins, Symmetry Energy, and Neutron Stars

Professor C.A. Bertulani, Texas A&M University-Commerce

    I will present a brief overview on the quest to determine the Equation of State (EoS) of neutron stars. Early experimental studies of pygmy resonances in neutron-rich nuclei will be discussed together with theoretical attempts to develop relationships between the properties of pygmy resonances and the EoS of neutron stars. Recent efforts to correlate neutron skins in nuclei and the EoS will also be presented. Focus will be given to microscopic descriptions of nuclei, how they predict diverse EoS, and how one can constrain their predictions by comparison with experiments at nuclear facilities and with astronomical observations [1-4].
