Title: Kepler equation for inspiralling compact binaries

Abstract

Compact binaries consisting of neutron stars/black holes on eccentric orbit undergo a perturbed Keplerian motion. The perturbations are either of relativistic origin or are related to the spin, mass quadrupole, and magnetic dipole moments of the binary components. The post-Newtonian motion of such systems decouples into radial and angular parts. We present here for the first time the radial motion of such a binary encoded in a generalized Kepler equation, with the inclusion of all above-mentioned contributions, up to linear order in the perturbations. Together with suitably introduced parametrizations, the radial motion is solved completely.

  • The standard adiabatic approximation to phasing of gravitational waves from inspiralling compact binaries uses the post-Newtonian expansions of the binding energy and gravitational wave flux both truncated at the same relative post-Newtonian order. Motivated by the eventual need to go beyond the adiabatic approximation we must view the problem as the dynamics of the binary under conservative post-Newtonian forces and gravitational radiation damping. From the viewpoint of the dynamics of the binary, the standard approximation at leading order is equivalent to retaining the 0PN and 2.5PN terms in the acceleration and neglecting the intervening 1PN and 2PN terms. A completemore » mathematically consistent treatment of the acceleration at leading order should include all PN terms up to 2.5PN without any gaps. These define the standard and complete non-adiabatic approximants, respectively. We propose a new and simple complete adiabatic approximant constructed from the energy and flux functions. At the leading order it uses the 2PN energy function rather than the 0PN one in the standard approximation so that in spirit it corresponds to the dynamics where there are no missing post-Newtonian terms in the acceleration. We compare the overlaps of the standard and complete adiabatic approximant templates with the exact waveform (in the adiabatic approximation) for a test particle orbiting a Schwarzschild black hole. Overlaps are computed using both the white-noise spectrum and the initial laser interferometer gravitational wave observatory (LIGO) noise spectrum. The complete adiabatic approximants lead to a remarkable improvement in the effectualness (i.e., larger overlaps with the exact signal) at lower PN (<3PN) orders. However, standard adiabatic approximants of order {>=}3PN are nearly as good as the complete adiabatic approximants for the construction of effectual templates. In general, faithfulness (i.e., smaller biases in the estimation of parameters) of complete approximants is also better than that of standard approximants. Standard and complete approximants beyond the adiabatic approximation are next studied using the Lagrangian models of Buonanno, Chen, and Vallisneri in the test mass limit. A limited extension of the results to the case of comparable mass binaries is provided. In this case, standard adiabatic approximants achieve an effectualness of 0.965 at order 3PN. If the comparable mass case is qualitatively similar to the test mass case then neither the improvement of the accuracy of energy function from 3PN to 4PN nor the improvement of the accuracy of flux function from 3.5PN to 4PN will result in a significant improvement in effectualness in the comparable mass case for terrestrial laser interferometric gravitational wave detectors.« less
  • We revisit the problem of parameter estimation of gravitational-wave chirp signals from inspiralling nonspinning compact binaries in the light of the recent extension of the post-Newtonian (PN) phasing formula to order (v/c){sup 7} beyond the leading Newtonian order. We study in detail the implications of higher post-Newtonian orders from 1PN up to 3.5PN in steps of 0.5PN ({approx}v/c), and examine their convergence. In both initial and advanced detectors the estimation of the chirp mass (M) and symmetric mass ratio ({eta}) improve at higher PN orders but oscillate with every half-a-PN order. In initial LIGO, for a 10M{sub {center_dot}}-10M{sub {center_dot}} binarymore » at a signal-to-noise ratio (SNR) of 10, the improvement in the estimation of M ({eta}) at 3.5PN relative to 2PN is {approx}19% (52%). We compare parameter estimation in different detectors and assess their relative performance in two different ways: at a fixed SNR, with the aim of understanding how the bandwidth improves parameter estimation, and for a fixed source, to gauge the importance of sensitivity. Errors in parameter estimation at a fixed SNR are smaller for VIRGO than for both initial and advanced LIGO. This is because of the larger bandwidth over which it observes the signals. However, for sources at a fixed distance it is advanced LIGO that achieves the lowest errors owing to its greater sensitivity. Finally, we compute the amplitude corrections due to the 'frequency-sweep' in the Fourier domain representation of the waveform within the stationary phase approximation and discuss its implication on parameter estimation. We find that the amplitude corrections change the errors in M and {eta} by less than 10% for initial LIGO at a signal-to-noise ratio of 10. Our analysis makes explicit the significance of higher PN order modeling of the inspiralling compact binary on parameter estimation.« less
  • Gravitational radiation drives compact binaries through an inspiral phase towards a final coalescence. For binaries with spin, mass quadrupole, and magnetic dipole moments, various contributions add to this process, which is characterized by the rate of increase df/dt of the gravitational wave frequency and the accumulated number N of gravitational wave cycles. We present here all contributions to df/dt and N up to the second post-Newtonian order. Among them we give for the first time the contributions due to the self-interaction of individual spins. These are shown to be commensurable with the proper spin-spin contributions for the recently discovered J0737-3039more » double pulsar and argued to represent the first corrections to the radiation reaction in the Lense-Thirring approach.« less
  • The matched filtering technique is used to search for gravitational wave signals of a known form in the data taken by ground-based detectors. However, the analyzed data contains a number of artifacts arising from various broad-band transients (glitches) of instrumental or environmental origin which can appear with high signal-to-noise ratio on the matched filtering output. This paper describes several techniques to discriminate genuine events from the false ones, based on our knowledge of the signals we look for. Starting with the {chi}{sup 2} discriminator, we show how it may be optimized for free parameters. We then introduce several alternative vetoingmore » statistics and discuss their performance using data from the GEO 600 detector.« less
