We consider the phase diagram of two-flavor quark matter under neutron star constraints for two nonlocal, covariant quark models within the mean field approximation. In the first one (Model I) the nonlocality arises from the regularization procedure, motivated by the instanton liquid model, whereas in the second model (Model II) a separable approximation of the one-gluon exchange interaction is applied. We find that Model II predicts a larger quark mass gap and a chiral symmetry breaking (CSB) phase transition line which extends 15-20% further into the phase diagram spanned by temperature (T) and chemical potential (mu). The corresponding critical temperature at mu=0, T_c(0)~140 MeV, is in better accordance to recent lattice QCD results tha...
