Metric perturbations produced by eccentric equatorial orbits around a Kerr black hole
We present the first numerical calculation of the (local) metric perturbation produced by a small compact object moving on an eccentric equatorial geodesic around a Kerr black hole, accurate to first order in the mass ratio. The procedure starts by first solving the Teukolsky equation to obtain the Weyl scalar ψ4 using semi-analytical methods. The metric perturbation is then reconstructed from ...
متن کاملGravitational self-force on eccentric equatorial orbits around a Kerr black hole
This paper presents the first calculation of the gravitational self-force on a small compact object on an eccentric equatorial orbit around a Kerr black hole to first order in the mass-ratio. That is the pointwise correction to the object’s equations of motion (both conservative and dissipative) due to its own gravitational field, which is treated as a linear perturbation to the background Kerr...
متن کاملRadiative Evolution of Orbits around a Kerr Black Hole
We propose a simple approach for the radiative evolution of generic orbits around a Kerr black hole. For a scalar-field, we recover the standard results for the evolution of the energy E and the azimuthal angular momentum Lz . In addition, our method provides a closed expression for the evolution of the Carter constant Q. Recently, the prospects of a direct observation of gravitational radiatio...

متن کاملEffect of gravitational radiation reaction on nonequatorial orbits around a Kerr black hole.
The effect of gravitational radiation reaction on orbits around a spinning black hole is analyzed. Such orbits possess three constants of motion: i , e , and a , which correspond, in the Newtonian limit of the orbit being an ellipse, to the inclination angle of the orbital plane to the hole’s equatorial plane, the eccentricity, and the semimajor axis length, respectively. First, it is argued th...
