Post-ISCO Ringdown Amplitudes in Extreme Mass Ratio Inspiral

General Relativity and Quantum Cosmology 2015-03-13 v4

Abstract

An extreme mass ratio inspiral consists of two parts: adiabatic inspiral and plunge. The plunge trajectory from the innermost stable circular orbit (ISCO) is special (somewhat independent of initial conditions). We write an expression for its solution in closed-form and for the emitted waveform. In particular we extract an expression for the associated black-hole ringdown amplitudes, and evaluate them numerically.
