| Abstract: | We construct phase diagrams of two-flavor quark matter under compact star constraints for two nonlocal, covariant quark models
(instanton liquid and one-gluon exchange (OGE) inspired) within the mean field approximation and compare the results for different
diquark coupling strengths. For the OGE model, stable hybrid stars with quark cores are obtained.
