Gravitational self-torque and spin precession in compact binaries
Sam R. Dolan, Niels Warburton, Abraham I. Harte +3
We calculate the effect of self-interaction on the "geodetic" spin precession of a compact body in a strong-field orbit around a black hole. Specifically, we consider the spin prec…
Stability of nonspinning effective-one-body model in approximating two-body dynamics and gravitational-wave emission
Yi Pan, Alessandra Buonanno, Andrea Taracchini +7
The detection of gravitational waves and the extraction of physical information from them requires the prediction of accurate waveforms to be used in template banks. For that purpo…
Effective-one-body model for black-hole binaries with generic mass ratios and spins
Andrea Taracchini, Alessandra Buonanno, Yi Pan +11
Gravitational waves emitted by black-hole binary systems have the highest signal-to-noise ratio in LIGO and Virgo detectors when black-hole spins are aligned with the orbital angul…
Impact of Higher Harmonics in Searching for Gravitational Waves from Non-Spinning Binary Black Holes
Collin Capano, Yi Pan, Alessandra Buonanno
Current searches for gravitational waves from coalescing binary black holes (BBH) use templates that only include the dominant harmonic. In this study we use effective-one-body mul…
Coalescence of binary neutron stars in a scalar-tensor theory of gravity
Masaru Shibata, Keisuke Taniguchi, Hirotada Okawa +1
We carry out numerical-relativity simulations of coalescing binary neutron stars in a scalar-tensor theory that admits spontaneous scalarization. We model neutron stars with realis…
Periastron advance in spinning black hole binaries: comparing effective-one-body and Numerical Relativity
Tanja Hinderer, Alessandra Buonanno, Abdul H. Mroué +8
We compute the periastron advance using the effective-one-body formalism for binary black holes moving on quasi-circular orbits and having spins collinear with the orbital angular…
