Erratum: Cauchy-horizon singularity inside perturbed Kerr black holes [Phys. Rev. D 93, 041501(R) (2016)]

摘要

In this Erratum we correct the behavior of the Weyl scalar ψ 4 and of the linearized curvature scalar K ? RαβγδRαβγδapproaching the mass-inflation singularity along an outgoing null direction. In the original paper we used a second-ordercode, that allowed us to find very accurately the fields in the exterior and on the event horizon. However, it has somedisadvantages approaching the Cauchy horizon (CH). Specifically, our code solves for Δ?2ψ 4, which diverges exponentiallywith advanced time approaching the CH (more specifically, diverges like e2v=M).
