Extreme mass ratio inspirals: LISA's unique probe of black hole gravity
Abstract
In this paper, I attempt to summarize past and present ongoing work on the problem of the inspiral of a small body in the gravitational field of a much more massive Kerr black hole. Such extreme mass ratio systems, expected to occur in galactic nuclei, will constitute prime sources of gravitational radiation for the future LISA gravitational radiation detector. The paper's main goal is to provide a survey of basic celestial mechanics in Kerr spacetime and calculations of gravitational waveforms and backreaction on the small body's orbital motion, based on the traditional 'fluxbalance' method and the Teukolsky black hole perturbation formalism.
