Semiclassical Effects in Color Flavor Locked Strange Stars

Strange stars in the color flavor locked phase, as described by a nonlinear generalization of the phenomenological MIT bag model proposed in the context of color superconductivity, are studied through a formalism motivated by the two semiclassical solutions for hydrostatic equilibrium. The semiclassical effects in the model are represented by a negative pressure fluid that might take place in the collapse of ultradense matter. Results show that within this framework it is possible to find ultracompact configurations situated between regular compact stars and black holes.
