On the anomalous mass defect of strange stars in the Field Correlator Method

Abstract

We investigate general aspects of the mass defects of strange stars in the context of the Field Correlator Method, without magnetic field. The main parameters of the model that enter the corresponding nonperturbative equation of state of the quark gluon plasma are the gluon condensate G2G_2 and the large distance static QQΛ‰Q{\bar Q} potential V1V_1. We calculate mass defects of stellar configurations in the central density range 11<log⁑ρc<1811<\log\rho_c<18. In general, the mass defects are strongly dependent on the model parameters. For a large range of values of G2G_2 and V1V_1, we obtain anomalous mass defects with magnitudes around 1053 10^{53}\,erg\,, of the same order of the observed energies of gamma-ray bursts and neutrino emissions in SN1987A, and of the theoretically predicted energies of the quark-novae explosions.Comment: 24 pages, 6 figure
