The problem of ultracompact rotating gravastars
arXiv:2009.12504 · doi:10.1103/PhysRevD.104.084041
Abstract
A number of authors provided arguments that a rotating gravastar is a good candidate for a source of the Kerr metric. These arguments were based on the second order perturbation analysis. In the following paper, we construct a perturbative solution of the rotating gravastar up to the third perturbation order and show that it cannot be continuously matched with the Kerr spacetime.
