[13.10] Low frequency gravitational waves from compact mass transfering binaries

Most studies of the galactic gravitational wave background in the low frequency gravitational wave band (~ 10 microHertz to ~ 100 milliHertz) focus on the contributions of detached binaries. The galactic background, however, will consist of many subpopulations, each of which may have important characteristics which can be probed by a gravitational wave observatory like LISA (Laser Interferometer Space Antenna). This study considers a population synthesis model for double compact remnants, and examines the contribution of compact mass transferring binaries to the low frequency gravitational wave spectrum, both as individually resolvable systems and as a source of confusion from overlapping binary signals. Particular emphasis is paid to the overall gravitational wave luminosity from this population, as opposed to restricting attention purely to the number of mass transferring systems, as has been done in previous studies.
