Addressing the spin question in gravitational-wave searches: Waveform templates for inspiralling compact binaries with nonprecessing spins
This paper presents a post-Newtonian (PN) template family of gravitational waveforms from inspiralling compact binaries with nonprecessing spins, where the spin effects are described by a single ‘‘reducedspin’’ parameter. This template family, which reparametrizes all the spin-dependent PN terms in terms of the leading-order (1.5PN) spin-orbit coupling term in an approximate way, has very high ...
متن کاملSpin effects in the phasing of gravitational waves from binaries on eccentric orbits
We compute here the spin-orbit and spin-spin couplings needed for an accurate computation of the phasing of gravitational waves emitted by comparable-mass binaries on eccentric orbits at the second post-Newtonian (PN) order. We use a quasi-Keplerian parametrization of the orbit free of divergencies in the zero-eccentricity limit. We find that spin-spin couplings induce a residual eccentricity f...
متن کاملTowards models of gravitational waveforms from generic binaries: II. Modelling precession effects with a single effective precession parameter
Gravitational waves (GWs) emitted by generic black-hole binaries show a rich structure that directly reflects the complex dynamics introduced by the precession of the orbital plane, which poses a real challenge to the development of generic waveform models. Recent progress in modelling these signals relies on an approximate decoupling between the nonprecessing secular inspiral and a precession-...
متن کاملA sparse representation of gravitational waves from precessing compact binaries
Many relevant applications in gravitational wave physics share a significant common problem: the seven-dimensional parameter space of gravitational waveforms from precessing compact binary inspirals and coalescences is large enough to prohibit covering the space of waveforms with sufficient density. We find that by using the reduced basis method together with a parametrization of waveforms base...
متن کاملFinal spins from the merger of precessing binary black holes
The inspiral of binary black holes is governed by gravitational radiation reaction at binary separations r & 1000M, yet it is too computationally expensive to begin numerical-relativity simulations with initial separations r * 10M. Fortunately, binary evolution between these separations is well described by postNewtonian equations of motion. We examine how this post-Newtonian evolution affects ...
