Multipolar analysis of spinning binaries

摘要: We present a preliminary study of the multipolar structure gravitational radiation from spinning black hole binary mergers. consider three different configurations: (1) one 'hang-up' run, where holes have equal masses and large spins initially aligned with orbital angular momentum; (2) seven 'spin-flip' runs, mass ratio q ≡ M1/M2 = 4, are anti-aligned momentum, initial Kerr parameters j1 j2 ji (where j J/M2) fine-tuned to produce Schwarzschild remnant after merger; (3) 'super-kick' runs 1, 2, 4 two located on plane, pointing in opposite directions. For all these simulations we compute energy distribution parameter final hole. hang-up show that including leading-order spin–orbit spin–spin terms decomposition post-Newtonian waveforms improves agreement numerical simulation.
