Abstrakt: | The strange quark star is investigated within the enlarged SU(3) Nambu-Jona-Lasinio model. The stable quark star can exist until a maximal configuration with ρm = 3.1 × 1015 g cm -3 with Mm = 1.61 M⊙ and Rm = 8.74 km is reached. Strange quarks appear for density above ρc = 9.84 g cm-3 for the quark star with radius Rc = 8.003 km and Mc = 0.77M⊙. A comparison of quark star properties obtained in the quark mean-field approach to a neutron star model constructed within the relativistic mean-field theory is presented. |
