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 ρ m = 3.1 × 10 15 g cm -3 with M m = 1.61 M ⊙ and R m = 8.74 km is reached. Strange quarks appear for density above ρ c = 9.84 g cm -3 for the quark star with radius R c = 8.003 km and M c = 0.77 M ⊙ . 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.
