Abstract

Using the Color-Dielectric model to describe quark confinement, including strange quarks and accounting for beta--equilibrium, we get masses for a static neutron star in the range 1.3≤ M/M\odot≤ 1.54 for a radius R≈ 9 km. Rapid cooling through the direct URCA mechanism is obtained. The implications for the composition of neutron stars is discussed.
