The high density QCD phase transition in compact stars — •Giuseppe Pagliara1, Matthias Hempel1, Irina Sagert2, and Jurgen Schaffner-Bielich1 — 1Institut für Theoretische Physik, Ruprecht-Karls-Universität, Philosophenweg 16, D-69120, Heidelberg, Germany — 2Institut für Theoretische Physik, Johann Wolfgang Goethe-Universität, Max von Laue–Str. 1, D-60438 Frankfurt, Germany
The study of the QCD phase diagram at high density is still in its infancy. A promising source of experimental informations comes from the physics of neutron stars, the core of which might reach densities up to ten times nuclear matter density. We review the different possible signals from neutrons stars which bring informations about the equation of state of strongly interacting matter from their birth, in a Supernova explosion [1], to the deleptonization era [2] and the early or late cooling, to eventually their final instants of life within the merger process in binary systems [3]. A special emphasis will be put on the modeling of the equation of state of matter from sub-saturation densities up to the large densities at which the chiral phase transition is believed to occur.
