Masses and radii of neutron and quark stars
arXiv:1004.0325
Abstract
We discuss new limits on masses and radii of compact stars and we conclude that they can be interpreted as an indication of the existence of two classes of stars: "normal" compact stars and "ultra-compact" stars. We estimate the critical mass at which the first configuration collapses into the second.
