Rastall's theory of gravity: Spherically symmetric solutions and the stability problem
K. A. Bronnikov, Júlio C. Fabris, Oliver F. Piattella +2
We study the stability of static, spherically symmetric solutions of Rastall's theory in the presence of a scalar field with respect to spherically symmetric perturbations. It is s…

Quasi-normal modes of black holes and naked singularities: revisiting the WKB method
Edison C. Santos, Júlio C. Fabris, José A. de Freitas Pacheco
In this paper we revisit the analysis of the ringdown frequencies in the form of quasi-normal modes for Schwarzschild,Schwarzschild de-Sitter and Reissner-Nordström space-times. We…
