The radial action for massive particles in spherically symmetric geometries: Exact resummation at any PM order
Donato Bini, Giorgio Di Russo
The paper derives exact, resummed expressions for the radial action of massive particles on hyperbolic-like geodesics in various spherically symmetric spacetimes, linking the resul…
5d Schwarzschild-Tangherlini spacetime: MST-like formalism for a Reduced Confluent Heun Equation
Donato Bini, Giorgio Di Russo, Veronica Fantini
The paper studies the five‑dimensional Schwarzschild‑Tangherlini black hole, analyzing its geodesic scattering, Lyapunov exponents for circular orbits, and massless scalar perturba…
Gravitational waveform from radial infall at the third-and-half Post-Newtonian order
Giorgio Di Russo, Donato Bini
We compute the gravitational waveform associated with a radially infalling particle in a Schwarzschild black hole working in the center-of-mass system and in a post-Newtonian (PN)…
Analytic self-force effects on radial infalling particles in the Schwarzschild spacetime: the radiated energy
Donato Bini, Giorgio Di Russo
We compute, at the first self force accuracy level, the radiated energy from a radially infalling particle released from rest in a Schwarzschild spacetime. We examine both the case…
Radial fall: the gravitational waveform up to the second-and-half Post-Newtonian order
Donato Bini, Giorgio Di Russo
We consider an application of the Multipolar Post Minkowskian formalism to the case of a two-body system in radial fall. We compute, within the post-Newtonian approximation, the as…
Scalar self-force effects in neutral -soliton backgrounds
Massimo Bianchi, Donato Bini, Giorgio Di Russo
We investigate several geometrical and physical properties of the recently found -soliton solution (neutral case). We discuss both the genuine 5d solution and its reduction to 4…
