Description
The quark-hadron phase transitions in issospin-asymmetric nuclear matter at zero temperature is described within a potential model using a cluster-Hartree-Fock approach. Stiffness and asymmetry energy of the nuclear matter are caused by the Pauli exclusion principle for the nucleon constituents. The coexistence region of quark-neutron matter covers the range 2.3-3.1 ρ0. A stable neutron star branch, with maximum mass of 2.20 Msun and with quark core radii of about 3 km, is obtained by integration of the Tolman-Oppenheimer-Volkoff equations. 20 refs.; 3 figs
