The problem of ultracompact rotating gravastars (2009.12504v2)

Published 26 Sep 2020 in gr-qc

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.
