Cold quark stars from hot lattice QCD
arXiv:0912.2827
Abstract
Based on a quasiparticle model for βstable 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. We find rather small radii and masses of equilibrium configurations composed of cold deconfined matter, well distinguished from neutron or hybrid stars.
