Abstract

Currently most of known stellar mass black holes have masses around seven solar masses, far exceeding the mass upper limit for a neutron star, which is around three solar masses. The LC equivalent potential is too small compare to strong interaction potential, so that gravity is usually ignored inside a strange star. We use the MIT bag model of quark matter, and assume the density in the bare strange star is a constant. We consider the scenario in which the mass of the strange star grows until its last stable orbit exceeds its radius. At this point the gravity inside the strange star becomes important and the strange star will quickly collapse into a black hole when it spins down.
