Structure of Stars and Nuclei

The properties of dense hadronic and quark matter and its relation to compact stars are discussed. In a bottom-up approach one starts with nuclear and hypernuclear physics at low density and extrapolates hadronic matter to large densities. The matching to the quark matter phase is performed in a top-down approach starting at asymptotically large densities. Implications for the mass-radius relation of compact stars and the existence of a new family of solutions will be outlined
