We study the matching of a general spherically symmetric spacetime with a Vaidya–Reissner–Nordström solution. To that end, we analyse the properties of spherically symmetric electromagnetic fields and develop the proper gravitational and electromagnetic junction conditions. We prove that generic spherically symmetric spacetimes can be matched to a Vaidya–Reissner–Nordström solution or one of its specializations, and that these matchings have clear physical interpretations. Furthermore, the non-spacelike nature of the matching hypersurface is proved under very general hypotheses. We obtain the fundamental result that any spherically symmetric body, be it in evolution or not, has an upper limit for the total net electric charge that is carried.
