Relativistic orbits with gravitomagnetic corrections

S. Capozziello, M. De Laurentis, F. Garufi +1

Corrections to the relativistic orbits are studied considering higher order approximations induced by gravitomagnetic effects. We discuss in details how such corrections come out t…

Constraining Post-Newtonian f(R) Gravity in the Solar System

Matteo Luca Ruggiero, Lorenzo Iorio

We consider some models of f(R) gravity that can be used to describe, in a suitable weak-field limit, the gravitational field of the Sun. Using a perturbative approach, we focus on…

Gravitomagnetic effects in Kerr-de Sitter space-time

Lorenzo Iorio, Matteo Luca Ruggiero

We explicitly worked out the orbital effects induced on the trajectory of a test particle by the the weak-field approximation of the Kerr-de Sitter metric. It results that the node…

Emission vs Fermi coordinates: applications to relativistic positioning systems

Donato Bini, Andrea Geralico, Matteo Luca Ruggiero +1

A 4-dimensional relativistic positioning system for a general spacetime is constructed by using the so called "emission coordinates". The results apply in a small region around the…

Gravito-magnetic gyroscope precession in Palatini f(R) gravity

Matteo Luca Ruggiero

We study gravito-magnetic effects in the Palatini formalism of f(R) gravity. On using the Kerr-de Sitter metric, which is a solution of f(R) field equations, we calculate the impac…

Gravitational waves from hyperbolic encounters

S. Capozziello, M. De Laurentis, F. De Paolis +2

The emission of gravitational waves from a system of massive objects interacting on hyperbolic orbits is studied in the quadrupole approximation. Analytic expressions are derived f…
