Progress Report: Cold quarks stars from hot lattice QCD

Based on a quasiparticle model for �� 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.
