Do we really need search templates for gravitational waves from compact binaries moving in inspiralling eccentric orbits ? — •Wen Linqing1, Alessandra Buonanno2, and Achamveedu Gopakumar3 — 1Max Planck Institut für Gravitationsphysik Albert-Einstein-InstitutAm Muehlenberg 1D-14476 Golm Germany — 2groupe de Gravitation et Cosmologie (GReCO), IAP ,98bis Boulevard ARago, 75014 Paris, France — 3Theoretisch-Physikalisches Institut, FSU, Max-Wien-Platz 1, 07743 Jena, Germany
Gravitational waves from compact binaries moving in inspiralling eccentric orbits are plausible sources of gravitational radiation for ground-based interferometric detectors, especially for detectors with good sensitivity at low frequency, such as VIRGO and Advanced LIGO. By using as target signals the current, most accurate post-Newtonian waveforms for inspiralling eccentric binaries, we evaluate the loss in signal-to-noise ratio if post-Newtonian templates for compact binaries in quasi-circular orbits were used. We explore how the loss in signal-to-noise depends on initial eccentricity, individual masses and post-Newtonian orders
