Cold quark stars from hot lattice QCD — •Robert Schulze1,2 und Kämpfer Burkhard1,2 — 1Forschungszentrum Dresden-Rossendorf, PF 510119, 01314 Dresden, Germany — 2TU Dresden, Institut für Theoretische Physik, 01062 Dresden, Germany
Based on a quasiparticle model for β stable and electrically neutral deconfined matter we address the mass-radius relation of pure quark stars. The model is adjusted to recent hot lattice QCD results for 2+1 flavors with almost physical quark masses [1]. We find rather small radii and masses of equilibrium configurations composed of cold deconfined matter, well distinguished from neutron or hybrid stars.
