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 ψ4 and of the linearized curvature scalar K := R_(αβγδ)R~(αβγδ) approaching the mass-inflation singularity along an outgoing null direction. In the original paper we used a second-order code, that allowed us to find very accurately the fields in the exterior and on the event horizon. However, it has some disadvantages approaching the Cauchy horizon (CH). Specifically, our code solves for Δ~(?2)ψ_4, which diverges exponentially with advanced time approaching theCH(more specifically, diverges like e~(2v/M)). Moreover, in the code's coordinates this field.
