متن کاملHorizon-absorption effects in coalescing black-hole binaries: An effective-one-body study of the nonspinning case
We study the horizon absorption of gravitational waves in coalescing, circularized, nonspinning blackhole binaries. The horizon-absorbed fluxes of a binary with a large mass ratio (q 1⁄4 1000) obtained by numerical perturbative simulations are compared with an analytical, effective-one-body (EOB) resummed expression recently proposed. The perturbative method employs an analytical, linear in the...
متن کاملGravitational wave background from coalescing compact stars in eccentric orbits
Stochastic gravitational wave background produced by a stationary coalescing population of binary neutron stars in the Galaxy is calculated. This background is found to constitute a confusion limit within the LISA frequency band up to a limiting frequency νlim ∼ 10 −3 Hz, leaving the frequency window ∼ 10–10 Hz open for the potential detection of cosmological stochastic gravitational waves and ...
متن کاملComment on a relativistic model for coalescing neutron star binaries
The Wilson approximate dynamics and the Einstein dynamics are compared for binary systems. At the second post-Newtonian approximation, genuine two-body aspects are found to differ by up to 114%. In the regime of a formal innermost stable circular orbit (ISCO) the both dynamics differ by up to 7%. Recently Wilson and Mathews [1] proposed a truncated version of the Einstein field equations to tre...
متن کاملEccentric orbits and QPOs in neutron star X-ray binaries
We investigate the suggestion that the frequencies of the kilohertz and other QPOs in the emission from neutron stars in low-mass X-ray binaries are generated by geodesic motion of gas clumps around the star. First we assume, following previous work, that the dominant frequencies produced by such motions are the azimuthal frequency ν K , the apsidal precession frequency ν AP , and the first ove...
