Title:	High density nuclear EoS and compact stars
Abstract:	Recently, observations of compact stars have provided new data of high accuracy which put strong constraints on the high-density behaviour of the equation of state of strongly interacting matter otherwise not accessible in terrestrial laboratories. The evidence for neutron stars with high mass ($M =2.1 \pm 0.2 ~M_{\odot}$ for PSR J0751+1807) and large radii ($R > 12$ km for RX J1856-3754) rules out soft equations of state and has provoked a debate whether the occurence of quark matter in compact stars can be excluded as well. In this contribution it is shown that modern quantum field theoretical approaches to quark matter including color superconductivity and a vector meanfield allow a microscopic description of hybrid stars which fulfill the new, strong constraints. For these objects color superconductivity turns out to be essential for a successful description of the cooling phenomenology in accordance with recently developed tests. We present implications for the QCD phase diagram to be explored in future generations of nucleus-nucleus collision experiments at low temperatures and high baryon densities such as CBM @ FAIR.
