Depletion of energy from Naked Singular regions during gravitational collapse
S. Jhingan, I. H. Dwivedi, S. Barve
A distinguishable and observable physical property of Naked Singular Regions of the spacetime formed during a gravitational collapse has important implications for both experimenta…
Appearance of the central singularity in spherical collapse
S. S. Deshingkar, P. S. Joshi, I. H. Dwivedi
We analyze here the structure of non-radial nonspacelike geodesics terminating in the past at a naked singularity formed as the end state of inhomogeneous dust collapse. The spectr…
Naked Singularity, Black-hole and the Mass Loss in a Spherically Symmetric Gravitational Collapse
I. H. Dwivedi
A distinguishable physical property between a naked singularity and a black-hole, formed during a gravitational collapse has important implications for both experimental and theore…
A Tolman-Bondi-Lemaitre Cell-Model for the Universe and Gravitational Collapse
A. Chamorro, S. S. Deshingkar, I. H. Dwivedi +1
A piecewise Tolman-Bondi-Lemaitre (TBL) cell-model for the universe incorporating local collapsing and expanding inhomogeneities is presented here. The cell-model is made up of TBL…
Photon redshift and the appearance of a naked singularity
I. H. Dwivedi
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 colla…
Initial data and the end state of spherically symmetric gravitational collapse
P. S. Joshi, I. H. Dwivedi
Generalizing earlier results on the initial data and the final fate of dust collapse, we study here the relevance of the initial state of a spherically symmetric matter cloud towar…
Field of a Radiation Distributuion
I. H. Dwivedi
General relativistic spherically symmetric matter field with a vanishing stress energy scalar is analyzed. Procedure for generating exact solutions of the field equations for such…
Initial Data and the Final Fate of Inhomogeneous Dust Collapse
I. H. Dwivedi, P. S. Joshi
We examine here the relevance of the initial state of a collapsing dust cloud towards determining it's final fate in the course of a continuing gravitational collapse. It is shown…
On the Occurrence of Naked Singularity in Spherically Symmetric Gravitational Collapse
I. H. Dwivedi, P. S. Joshi
Generalizing earlier results of Joshi and Dwivedi (Commun. Math. Phys. 146, 333 (1992); Lett. Math. Phys. 27, 235 (1993)), we analyze here the spherically symmetric gravitational c…
