Gravitational Waves from Inspiralling Compact Binaries in ... - LUTH

Earlier Work
∗ GW from an eccentric binary, during that stage of inspiral
where the GRR is so small that the orbital parameters can
be treated as essentially unchanging over a few orbital
periods (‘adiabatic approx’).
∗ Damour, Gopakumar and Iyer (2004) Analytic method
for constructing high accuracy templates for the GW sig-
nals from the inspiral phase of compact binaries moving on
quasi-elliptical orbits by improved “method of variation of
constants” to combine the three time scales involved in the
elliptical orbit case, namely, orbital period, periastron pre-
cession and radiation reaction time scales, without making
the usual approximation of treating the radiative time scale
as an adiabatic process.
