Abstract

We treat the phenomenon of a γ-ray burst as the non-linear collapse of a magnetic cavity surrounding a neutron star with extremely large magnetic field B∼1015–1016 G due to the process of bubble shape instability in the resonant MHD field of an accreting plasma or on a neutron star surface. The QED effect of vacuum polarizability by a strong magnetic field is taken into a consideration. We develop an analogy with the phenomenon of sonoluminescence in which the gas bubble is located in a surrounding liquid with a driven sound intensity.
