8 Oct 2004 | | Journal: | Phys.Rev. D70 (2004) 084038 | | Subject: | gr-qc | | Abstract: | We construct a class of spherically symmetric collapse models in which a naked singularity may develop as the end state of collapse. The matter distribution considered has negative radial and tangential pressures, but the weak energy condition is obeyed throughout. The singularity forms at the center of the collapsing cloud and continues to be visible for a finite time. The duration of visibility depends on the nature of energy distribution. Hence the causal structure of the resulting singularity depends on the nature of the mass function chosen for the cloud. We present a general model in which the naked singularity formed is timelike, neither pointlike nor null. Our work represents a step toward clarifying the necessary conditions for the validity of the Cosmic Censorship Conjecture. | | Source: | arXiv, gr-qc/0410041 | | Services: | Forum | Review | PDF | Favorites | |
