Tidal effects in the total flux and waveform in massless scalar-tensor theories to, respectively, relative 2PN and 1.5PN orders

Eve Dones, Laura Bernard

Within scalar-tensor (ST) theories, neutron stars in binary systems experience tidal deformations caused by both their companion and the scalar field. These deformations are strong…

Tidal effects up to next-to-next-to leading post-Newtonian order in massless scalar-tensor theories

Laura Bernard, Eve Dones, Stavros Mougiakakos

In this article, we study the tidal effects in the gravitationally bound two-body system at next-to-next-to leading post-Newtonian order for spin-less sources in massless scalar-te…

Analytical Solution of Spinning, Eccentric Binary Black Hole Dynamics at the Second Post-Newtonian Order

Tom Colin, Sashwat Tanay, Laura Bernard

Recent gravitational wave (GW) detections showing signatures of eccentricity and spin precession underscore the need to model binary black holes (BBHs) possessing these features si…

Scattering angle at 3PM in scalar-tensor theories using the PM-EFT formalism

Laura Bernard, Tamanna Jain, Stavros Mougiakakos

In this work, we derive the conservative dynamics of non-spinning binaries in the massless scalar-tensor theories using the post-Minkowskian Effective Field Theory (EFT) approach.…

Generic EFT-motivated beyond General Relativity gravitational wave tests and their curvature dependence: from observation to interpretation

Laura Bernard, Suvendu Giri, Luis Lehner +1

We present a "dictionary" to expedite the identification of potential deviations in gravitational waveforms from those predicted by General Relativity (GR) during the inspiral phas…

Tidal contributions to the full gravitational waveform to the second-and-a-half post-Newtonian order

Eve Dones, Quentin Henry, Laura Bernard

This paper describes the different steps to include the adiabatic tidal effects to the gravitational waveform amplitude for quasi-circular non-spinning compact binaries up to the s…
