When a particle moves around a Kerr black hole, it radiates gravitational waves. Some of these waves are absorbed by the black hole. We calculate such absorption of gravitational waves induced by aâ€¦ (More)

Extending a method developed by Sasaki in the Schwarzschild case and by Shibata, Sasaki, Tagoshi, Tanaka in the Kerr case, we calculate the post-Newtonian expansion of the gravitational waveâ€¦ (More)

Using the Teukolsky and Sasaki-Nakamura equations for the gravitational perturbation of the Kerr spacetime, we calculate the post-Newtonian expansion of the energy and angular momentum luminositiesâ€¦ (More)

We discuss a numerical method to compute the homogeneous solutions of the Teukolsky equation which is the basic equation of the black hole perturbation method. We use the formalism developed by Mano,â€¦ (More)
