5 Gravitational Waves from a Particle Orbiting a Black Hole

Based on the ingoing wave functions discussed in Section 3 and 4, we can derive the gravitational wave energy and angular momentum flux emitted to infinity. The formula for the energy and the angular momentum luminosity to infinity are given by Equations (48View Equation) and (49View Equation). Since most of the calculations are very long, we show only the final results. In [71Jump To The Next Citation Point], some details of the calculations are summarized. We define the post-Newtonian expansion parameter by x ≡ (M Ωφ )1∕3, where M is the mass of the black hole and Ω φ is the orbital angular frequency of the particle. Since the parameter x is directly related to the observable frequency, this result can be compared with the results by another method easily.
