Abstract
A brief review is given on compact binaries as sources of gravitational waves and their detection with ground based detectors, followed by a survey of the various techniques used to model them in the binary parameter space. The future space based interferometer, LISA, will have different kinds of compact binaries as prime targets. These binaries comprise a stellar-mass compact object orbiting about a supermassive black hole. These extreme-mass-ratio inspirals as they are known, are a particularly interesting source of gravitational waves, and modelling these systems requires different methods to those that have enabled current detections. A historical survey is then given on the concept of a small object moving in a curved spacetime, when its motion is influenced by interaction with its own gravitational field. This is followed by a presentation of some basic concepts in self-force theory and its use in modelling such systems.
