Shifted-geodesic approximation for spinning-body gravitational wave fluxes

Lisa V. Drummond, Scott A. Hughes, Viktor Skoupý +2

We present a shifted-geodesic framework for computing gravitational-wave fluxes from spinning test bodies moving on bound orbits of Kerr black holes. The method provides a simple a…

Going into a tailspin near the abyss: analytic solutions for spinning particles on near equatorial, plunging orbits in Kerr spacetime

Gabriel Andres Piovano

This work presents, the first time, analytic solutions for the nearly equatorial, plunging motion of a spinning test-particle in Kerr spacetime. The equations of motion are solved…

Spin-aligned inspiral waveforms from self-force and post-Newtonian theory

Loïc Honet, Josh Mathews, Geoffrey Compère +5

We present the state-of-the-art waveform model WaSABI-C for quasicircular inspirals of spinning black hole binaries with aligned or anti-aligned spins. Our model synthesizes the mo…

Particles with precessing spin in Kerr spacetime: analytic solutions for eccentric orbits and homoclinic motion near the equatorial plane

Gabriel Andres Piovano

We present a family of analytic solutions for the nearly-equatorial motion of a test particle with precessing spin in Kerr spacetime. We solve the equations of motion up to linear…

Spherical inspirals of spinning bodies into Kerr black holes

Viktor Skoupý, Gabriel Andres Piovano, Vojtěch Witzany

Extreme mass-ratio inspirals (EMRIs), consisting of a stellar-mass compact object spiraling into a massive black hole, are key sources for future space-based gravitational wave obs…

Spinning particles near Kerr black holes: Orbits and gravitational-wave fluxes through the Hamilton-Jacobi formalism

Gabriel Andres Piovano, Christiana Pantelidou, Jake Mac Uilliam +1

Extreme mass-ratio inspirals are among the key sources of gravitational waves for the Laser Interferometer Space Antenna space-based gravitational-wave detector. Achieving sufficie…
