An Efficient Numerical Method for Computing Gravitational Waves Induced by a Particle Moving on Eccentric Inclined Orbits around a Kerr Black Hole
Ryuichi Fujita, Wataru Hikida, Hideyuki Tagoshi
We develop a numerical code to compute gravitational waves induced by a particle moving on eccentric inclined orbits around a Kerr black hole. For such systems, the black hole pert…
The adiabatic evolution of orbital parameters in the Kerr spacetime
Norichika Sago, Takahiro Tanaka, Wataru Hikida +2
We investigate the adiabatic orbital evolution of a point particle in the Kerr spacetime due to the emission of gravitational waves. In the case that the timescale of the orbital e…
Adiabatic radiation reaction to the orbits in Kerr Spacetime
Norichika Sago, Takahiro Tanaka, Wataru Hikida +1
Geodesic motion of a point particle in Kerr geometry has three constants of motion, energy , azimuthal angular momentum , and Carter constant . Under the adiabatic approxi…
Self-force Regularization in the Schwarzschild Spacetime
Wataru Hikida, Hiroyuki Nakano, Misao Sasaki
We discuss the gravitational self-force on a particle in a black hole space-time. For a point particle, the full (bare) self-force diverges. The metric perturbation induced by a pa…
A new analytical method for self-force regularization II. Testing the efficiency for circular orbits
Wataru Hikida, Sanjay Jhingan, Hiroyuki Nakano +3
In a previous paper, based on the black hole perturbation approach, we formulated a new analytical method for regularizing the self-force acting on a particle of small mass orb…
A new analytical method for self-force regularization I. scalar charged particle in Schwarzschild spacetime
Wataru Hikida, Sanjay Jhingan, Hiroyuki Nakano +3
We formulate a new analytical method for regularizing the self-force acting on a particle of small mass orbiting a black hole of mass , where . At first order in …
