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…
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…
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…
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…
Resumming Post-Minkowskian and Post-Newtonian gravitational waveform expansions
Andrea Cipriani, Giorgio Di Russo, Francesco Fucito +3
We derive formulae that resum, at a given order in the soft limit, the infinite series of Post-Minkowskian (small gravitational coupling) or Post-Newtonian (small velocities) corre…
Charge (in)stability and superradiance of Topological Stars
Andrea Cipriani, Carlo Di Benedetto, Giorgio Di Russo +2
We study linear massive scalar charged perturbations of Topological Stars in the fuzzball and in the black hole (Black String) regimes. The objects that naturally couple to the ele…
