Screening of the Reissner–Nordström charge by a thin-shell of dust matter

Abstract: A concentric charged thin-shell encircling a Reissner-Nordström black hole screens the electric/magnetic charge completely to match with an external Schwarzschild black hole. The negative mass thin-shell is shown to be stable against radial perturbations. It is shown further that by reversing the roles of inside Reissner-Nordström and outside Schwarzschild geometries the mass of the appropriate shell becomes positive.

“…which shows the consistency of the physical configuration. Physically equations (43) and (44) imply that with the particles at the TSW's throat non-interacting, if  < a 0 0 since ̈< a 0 the throat will experience an accelerated collapse until a=0. The total finite time needed for the process of collapsing to happen is simply given by equation (44) i.e.,…”

“…We should add that thin shells of dust have been considered in the literature. For instance, Zloshchastiev considered monopole and electrically charged dust thin shells in general relativity in [41], F. Mercati et al studied the gravitational collapse of thin shells of dust in asymptotically flat shape dynamics in [42] and Mazharimousavia, and Halilsoy worked on screening of the Reissner-Nordström charge by a thin-shell of dust matter in [43].…”
