Interacting white dwarf binary systems (IWDBs) are the most promising guaranteed source sof continuous detectable gravitational radiation for the proposed space-based laser interferometric gravity wave detector, OMEGA. The galactic space density and frequency distribution of IWDBs depends on their time evolution. This project aims to develop models of mass transfer between the components of the binary system and mass loss from the system as a whole. These models are expected to trace the evolution of IWDBs from initial Roche lobe contact of a close white dwarf binary to the eventual coalescence or disruption of the system. The models will be compared with the six known IWDBs to determine their place along the evolutionary track and to then infer the birth rate and frequency distribution of these systems. Comparison with models of close white dwarf binary space densities will then yield the space density of IWDBs.
