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

Authors:

Andrew Mummery, Steven Balbus

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.
