Inspirals from the innermost stable circular orbit of Kerr black holes: exact solutions and universal radial flow
Physical Review Letters American Physical Society 129:16 (2022) 161101
Abstract:
We present exact solutions of test particle orbits spiraling inward from the innermost stable circular orbit (ISCO) of a Kerr black hole. Our results are valid for any allowed value of the angular momentum a parameter of the Kerr metric. These solutions are of considerable physical interest. In particular, the radial four-velocity of these orbits is both remarkably simple and, with the radial coordinate scaled by its ISCO value, universal in form, otherwise completely independent of the black hole spin.Testing afterglow models of FRB 200428 with early post-burst observations of SGR 1935+2154
