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…
