Radiative losses from unbound orbits at quadratic order in spin from MPM formalism
Donato Bini, Giorgio Di Russo
We study the spinning two-body system in the aligned spin case for hyperboliclike motions computing all radiative losses (at the 2PN absolute accuracy and including spin-squared co…
The radial action for massive particles in spherically symmetric geometries: Exact resummation at any PM order
Donato Bini, Giorgio Di Russo
We compute the massive particles radial action along hyperboliclike geodesics in various spherically symmetric spacetimes: the standard Schwarzschild spacetime, its -dimens…
5d Schwarzschild-Tangherlini spacetime: MST-like formalism for a Reduced Confluent Heun Equation
Donato Bini, Giorgio Di Russo, Veronica Fantini
We study the five-dimensional Schwarzschild-Tangherlini solution, with particular attention to its geodesic structure and massless scalar perturbations. In the probe limit, we pres…
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)…
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…
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…
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…
Kerr spacetime and scalar wave equation: Exact resummation of the renormalized angular momentum in the eikonal limit
Donato Bini, Giorgio Di Russo, Andrea Geralico
We show that the null geodesic radial action for unbound orbits in the Kerr spacetime, and consequently the scattering angle, can be resummed in terms of hypergeometric functions,…
Topological Stars and scalar wave equation: Exact resummation of the renormalized angular momentum in the eikonal limit
Donato Bini, Giorgio Di Russo
We show that for a Topological Star the renormalized angular momentum parameter, , appearing in the Mano-Suzuki-Takasugi-type or in the quantum-Seiberg-Witten-type approaches of…
Scattering angle in a Topological Star spacetime: a self-force approach
Massimo Bianchi, Donato Bini, Giorgio Di Russo
We compute the scattering angle for a scalar neutral probe undergoing unbound motion around a Topological Star, including self-force effects. Moreover we identify the `electro-magn…
Characterizing geodesic deviations in a Topological Star spacetime: massive, charged, spinning and stringy-like objects
Donato Bini, Giorgio Di Russo
We study deviations from geodesic motions in a Topological Star spacetime for either massive, charged and spinning particles, elucidating different behaviours with the Schwarzschil…
Scalar waves from unbound orbits in a TS spacetime: PN reconstruction of the field and radiation losses in a self-force approach
G. Di Russo, M. Bianchi, D. Bini
We analyze scalar wave emission from unbound orbits in a Topological Star spacetime. Our study uses a self-force approach and leads to a Post-Newtonian reconstruction of the field…
Scalar waves in a Topological Star spacetime: self-force and radiative losses
Massimo Bianchi, Donato Bini, Giorgio Di Russo
We study the radiated energy by a scalar particle moving on a circular orbit (smeared in the extra dimension) in the spacetime of a topological star, extending a previous study [Ph…
Scalar perturbations in a Top-Star spacetime
Massimo Bianchi, Donato Bini, Giorgio Di Russo
We discuss the dynamics of a (neutral) test particle in Topological Star spacetime undergoing scattering processes by a superposed test radiation field, a situation that in a 4D bl…
