Abstract: (arXiv)
Extending a method developed by Sasaki in the Schwarzschild case and by Shibata, Sasaki, Tagoshi, and Tanaka in the Kerr case, we calculate the post-Newtonian expansion of the gravitational wave luminosities from a test particle in circular orbit around a rotating black hole up to O(v 8)O(v~8) beyond the quadrupole formula. The orbit of a test particle is restricted on the equatorial plane. We find that spin dependent terms appear in each post-Newtonian order, and that at O(v 6)O(v~6) they have a significant effect on the orbital phase evolution of coalescing compact binaries. By comparing the post-Newtonian formula of the luminosity with numerical results we find that, for 30Mr100M30M\lesssim r \lesssim 100M, the spin dependent terms at O(v 6)O(v~6) and O(v 7)O(v~7) improve the accuracy of the post-Newtonian formula significantly, but those at O(v 8)O(v~8) do not improve.
