The quark strange star in the enlarged Nambu-Jona-Lasinio model

R. Mańka, G Przybyla

Abstract

The strange quark star is investigated within the enlarged SU(3) Nambu-Jona-Lasinio (NJL). The stable quark star exist from minimal central density rho_1=7.5 10^14 g/cm^3 with mass M=0.6822 M_Sun and radius R=19.52 km till maximal one rho_2=3.6 10^15 g/cm^3 with M=1.55 M_Sun and R=9.637 km.
