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…
