Abstract: | The phase structure and equation of state for two-flavor quark matter under compact star constraints is studied within a nonlocal
chiral quark model. Chiral symmetry breaking leads to rather large, density dependent quark masses at the phase transition
to quark matter. The influence of diquark pairing gaps and quark masses on density dependent emissivities for the direct URCA
is discussed. Since m
u
> m
d
, the direct URCA process due to quark masses cannot occur. We present cooling curves for model quark stars and discuss their
relation to observational data.
