Weightiness of the nuclear equation of state on the structure and formation of compact stars

We study the structure and the formation of compact stars for different nuclear equation of state. We show that, if color superconducting quark matter forms in hybrid stars, it is possible to satisfy most of recent observational boundaries on masses and radii of compact stellar objects. Moreover, a huge amount of energy, of the order of 1053 erg, can be released in the conversion from a (metastable) hadronic star into a (stable) hybrid or quark star, if the presence of a color superconducting phase is taken into account. Effects of nonconventional statistical mechanics are also discussed. (author)
