Radiation-reaction driven dynamics at the third-and-a-half post-Newtonian order in different gauges
Donato Bini, Andrea Geralico, Sara Rufrano Aliberti
We consider the coordinate-dependent definition of the radiation-reaction force at the third-and-a-half post-Newtonian order for general orbits. In order to (partially) determine i…
Radiation-reaction correction to scattering binary dynamics at the Next-to-Leading Post-Newtonian Order
Donato Bini, Andrea Geralico, Sara Rufrano Aliberti
We compute the next-to-leading-order radiation-reaction modification to the harmonic coordinate quasi-Keplerian parametrization of the binary dynamics, the two bodies undergoing a…
High-post-Newtonian-order dynamical effects induced by tail-of-tail interactions in a two body system
Donato Bini, Thibault Damour, Andrea Geralico
Starting from the recently derived conservative tail-of-tail action [D. Bini and T. Damour, arXiv:2504.20204 [hep-th]] we compute several dynamical observables of binary systems (D…
Post-Minkowskian self-force in the low-velocity limit: scalar field scattering
Donato Bini, Andrea Geralico, Chris Kavanagh +2
In this paper we present an approach to compute analytical post-Minkowskian corrections to unbound two-body scattering in the self-force formalism. Our method relies on a further l…
Conservative binary dynamics beyond order in electrodynamics
Donato Bini, Thibault Damour
We compute the conservative scattering angle of two classical charged particles at the sixth order in electromagnetic coupling, and at the fourth order in velocity, thereby going b…
Explicit solution of the gravitational two-body problem at the second post-Minkowskian order
Donato Bini, Thibault Damour, Andrea Geralico
The worldlines (in harmonic coordinates) of two gravitationally interacting massive bodies at the second post-Minkowskian order are described in explicit form. Both the conservativ…
