Abstract

It has been suggested that quark matter is superfluid (superconducting) at the high densities and/or temperatures characteristic of compact star interiors. We present the first calculations of compact star cooling including this phase, showing that the cooling behavior could be dramatically changed with respect to former studies including a normal quark core. Particularly, we find that some of the presented scenarios tend to be closer to the observational data and open the possibility of subsequently modeling the histories of all known young and medium-aged (i.e., without significant reheating) pulsars without having to postulate any fundamental difference between them. Moreover, improved observations might allow an astrophysical determination of the quark-matter critical temperature.
