Item Collapsing perfect fluid in self-similar five dimensional space-time and cosmic censorship(2011-07-06) Ghosh, S. G.; Sarwe, S. B.; Saraykar, R. V.We investigate the occurrence and nature of naked singularities in the gravitational collapse of a self-similar adiabatic perfect fluid in a five dimensional space-time. The naked singularities are found to be gravitationally strong in the sense of Tipler and thus violate the cosmic censorship conjecture.Item Collapsing shells of radiation in higher dimensional spacetime and cosmic censorship conjecture(2001-06-26) Ghosh, S. G.; Saraykar, R. V.; Beesham, A.Gravitational collapse of radiation shells in a non self-similar higher dimensional spherically symmetric spacetime is studied. Strong curvature naked singularities form for a highly inhomogeneous collapse, violating the cosmic censorship conjecture. As a special case, self similar models can be constructed.Item Higher Dimensional Radiation Collapse and Cosmic Censorship(2000-11-12) Ghosh, S. G.; Saraykar, R. V.We study the occurrence of naked singularities in the spherically symmetric collapse of radiation shells in a higher dimensional spacetime. The necessary conditions for the formation of a naked singularity or a black hole are obtained. The naked singularities are found to be strong in the Tipler’s sense and thus violating cosmic censorship conjecture.
