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 o…
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…
