Radially homothetic spacetime is of Petrov-type D
Sanjay M Wagh, Keshlan S Govinder
It is well-known \cite{mtbh} that {\em all} black hole solutions of General Relativity are of Petrov-type D. It may thus be expected that the spacetime of {\em physically realizabl…
What is the spacetime of {\em physically realizable} spherical collapse?
Sanjay M. Wagh, Ravindra V. Saraykar, Keshlan S. Govinder
We argue that a particular spacetime, a spherically symmetric spacetime with hyper-surface orthogonal, radial, homothetic Killing vector, is a physically meaningful spacetime that…
Radiating spherical collapse with heat flow
M. Govender
We present here a simple model of radiative gravitational collapse with radial heat flux which describes qualitatively the stages close to the formation of a superdense cold star.…
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…
