Naked singularities: Gravitationally collapsing configurations of dust or radiation in spherical symmetry, a unified treatment

It is shown that the naked singular solutions that form in the gravitational spherical collapse of radiation are of the same nature as the ones which form the collapse of dust matter. The stability, the strength, and other features of the singularities and Cauchy horizons are analyzed. This has implications in a possible formulation of the cosmic censorship hypothesis.
