Observational constraints on the Kerr and its several single-parameter modified spacetimes using quasi-periodic oscillation data
Abstract This paper investigates the dynamical effects of particles moving in the Kerr spacetime and its nine single-parameter modified spacetimes, including Bardeen, Ayon-Beato and Garcia (ABG), Hayward, Kerr–Newman (KN), Kerr–Taub–NUT (KTN), Braneworld Kerr (BK), Kerr-MOG, Kerr–Sen, and Perfect Fl...
