Perturbations of the Vaidya metric in the frequency domain: Quasinormal modes and tidal response
Lodovico Capuano, Luca Santoni, Enrico Barausse
Abstract
The authors have studies the dynamics of linear perturbations in the Vaidya metric, where the black hole has an evolving mass. They show that a clever change of variables enables one to study, despite the time dependence of the background, these perturbations in the frequency domain, at least for a certain range of frequencies. They go on to calculate the quasi-normal modes and tidal Love numbers in the Vaidya background.
