A new method to integrate (2+1)-wave equations with Dirac's delta functions as sources
Carlos O. Lousto, Hiroyuki Nakano
Unlike in the Schwarzschild black hole background, gravitational perturbations in a Kerr black hole background can not be decomposed into simple tensor harmonics in the time domain…
New method to integrate 2+1 wave equations with Dirac's delta functions as sources
Hiroyuki Nakano, Carlos O. Lousto
Gravitational perturbations in a Kerr black hole background can not be decomposed into simple tensor harmonics in the time domain. Here, we make the mode decomposition only in the…
Three-body equations of motion in successive post-Newtonian approximations
Carlos O. Lousto, Hiroyuki Nakano
There are periodic solutions to the equal-mass three-body (and N-body) problem in Newtonian gravity. The figure-eight solution is one of them. In this paper, we discuss its solutio…
Second Order Quasi-Normal Mode of the Schwarzschild Black Hole
Hiroyuki Nakano, Kunihito Ioka
We formulate and calculate the second order quasi-normal modes (QNMs) of a Schwarzschild black hole (BH). Gravitational wave (GW) from a distorted BH, so called ringdown, is well u…
Regular second order perturbations of extreme mass ratio black hole binaries
Hiroyuki Nakano, Carlos O. Lousto
We report on the first results of self-consistent second order metric perturbations produced by a point particle moving in the Schwarzschild spacetime. The second order waveforms s…
