Black hole ringdown from physically sensible initial value problem in higher-order scalar-tensor theories

Keisuke Nakashi, Masashi Kimura, Hayato Motohashi +1

We study odd-parity perturbations about static and spherically symmetric black hole solutions with a linearly time-dependent scalar field in higher-order scalar-tensor theories. In…

Black hole perturbations in higher-order scalar-tensor theories: initial value problem and dynamical stability

Keisuke Nakashi, Masashi Kimura, Hayato Motohashi +1

We propose a physically sensible formulation of initial value problem for black hole perturbations in higher-order scalar-tensor theories. As a first application, we study monopole…

Revisiting timelike geodesics in the Fisher-Janis-Newman-Winicour-Wyman spacetime

Keisuke Ota, Shinpei Kobayashi, Keisuke Nakashi

We investigate the timelike geodesics and the periapsis precession of orbits in the Fisher-Janis-Newman-Winicour-Wyman spacetime. This spacetime represents the naked singularity sp…
