Phys. Rev. D 58, 064004 (1998) [6 pages]Photon redshift and the appearance of a naked singularityReceived 17 March 1998; published 5 August 1998 In this paper we analyze the redshift as observed by an external observer receiving photons which terminate in the past at the naked singularity formed in a Tolman-Bondi dust collapse. Within the context of models considered here it is shown that photons emitted from a weak curvature naked singularity are finitely redshifted to an external observer whereas the strong curvature naked singularities are censored in the sense that photons escaping in such a scenario are infinitely redshifted. © 1998 The American Physical Society URL:
