Abstract: (arXiv)
Using the post-Newtonian (PN) expansion technique of the gravitational wave perturbation around a Schwarzschild black hole, we calculate analytically the energy flux of gravitational waves induced by a particle in circular orbits up to the 5.5PN order, i.e. O(v 11)O(v~{11}) beyond Newtonian. By comparing the formula with numerical data, we find that the error of the 5.5PN formula is about 4% when the particle is on the last stable circular orbit. We also estimate the error ΔN\Delta N in the total cycle of gravitational waves from coalescing compact binaries in a laser interferometer's band produced by using the post-Newtonian approximations. We find that, as for the neutron star-black hole binaries, the 4.5PN approximation gives \Delta N\alt1 for a black hole of mass M<40MM<40M_\odot, while it gives \Delta N\agt1 for a black hole of mass M>40MM>40M_{\odot}.
