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 d350e06da317a92252e" title="Click to view the MathML source">G₂$G_2$ and the large distance static $Q\overline{Q}$ potential V₁$V_1$.

We calculate mass defects of stellar configurations in the central density range 11<log⁡ρ_c<18$11<\log {\rho }_c<18$. In general, the mass defects are strongly dependent on the model parameters. For a large range of values of d350e06da317a92252e" title="Click to view the MathML source">G₂$G_2$ and V₁$V_1$, we obtain anomalous mass defects with magnitudes around 10⁵³ erg${10}^{53}\text{erg}$, 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.
