Abstract: | We have computed the energy ΔE, the momentum ΔP and the angular momentum ΔJ of gravitational radiation induced by a particle of mass μ and angular momentum μLz plunging into a Schwarzschild black hole of mass M (?μ). It is found that the maximum value of ΔP is 4.5 × 10?2 (μ/M) μc, ΔE/ΔJ ≈ 0.15c/(GM/c2), and a rotating ring plunging into a black hole emits less energy than a non-rotating one. |
