"EMRI Modeling in Perturbation Theory" 

J. Thompson 

Advances in gravitational wave detection systems continue to expand the range of possible signals that we may observe. These advances necessitate welldeveloped models of the physics behind detectable sources, in order to accurately produce waveforms of the gravitational radiation. In particular, many proposed spacebased gravitational wave antennae will resolve lower frequency signals than their groundbased counterparts. One prime lowfrequency source is the extreme massratio inspiral (EMRI), or the decaying orbit of a light body about a heavy body, ending eventually in merger. Modeling an EMRI system lies comfortably within the realm of perturbation theory. My talk will overview the methods used in perturbation theory to model EMRI systems, including the approaches and techniques currently being used to work toward secondorder results.
