INTERSECTIONS OF SELF-GRAVITATING CHARGED SHELLS IN A REISSNER-NORDSTROM FIELD

We describe the equation of motion of two charged spherical shells with tangential pressure in the field of a central Reissner-Nordstrom (RN) source. We solve the problem of determining the motion of the two shells after the intersection by solving the related Einstein-Maxwell equations and by imposing a physical continuity condition on the shells' velocities. In addition, we consider four applications: post-Newtonian and ultrarelativistic approximations, a test-shell case, and the ejection mechanism of one shell. This work is a direct generalization of Barkov-Belinski-Bisnovati-Kogan paper.
