Gravitational Collapse with Non–vanishing Tangential Stresses Ii: Extension to the Charged Case and General Solution

The exact solutions of the Einstein field equations describing spherically symmetric, ani-sotropic elastic spheres supported only by tangential stresses are generalized to the case of materials carrying a non–vanishing charge density. Using the mass–area system of coordinates first proposed by Ori for dust models, the general solution is then reduced to a very simple form in which only an integral remains to be performed. As a consequence, a simple approach to the problem of existence and nature of singularities is outlined, and a conjecture on the nature of the central singularity is formulated and motivated on physical grounds.
