Spherical Gravitational Collapse and Accretion - Exact General Relativistic Description
Sanjay M Wagh
In this paper, we consider the problems of spherical gravitational collapse and accretion using a spherically symmetric, spatially homothetic spacetime, that is, as an exact soluti…

Axially Symmetric, Spatially Homothetic Spacetimes
Sanjay M. Wagh, Keshlan S. Govinder
We show that the existence of appropriate spatial homothetic Killing vectors is directly related to the separability of the metric functions for axially symmetric spacetimes. The d…
