Black hole solutions of gravity theories with nonminimal coupling between matter and curvature
Orfeu Bertolami, Mariano Cadoni, Andrea Porru
We study black hole solutions in an extension of General Relativity (GR) with an explicit non-minimal coupling between matter and curvature. General black hole solutions satisfying…
Viability of nonminimally coupled f (R) gravity
Orfeu Bertolami, Jorge Páramos
In this work we explore the viability of nonminimally coupled matter- curvature gravity theories, namely the conditions required for the absence of tachyon instabilities and ghost…
Modelling the nongravitational acceleration during Cassini's gravitation experiments
O. Bertolami, F. Francisco, P. J. S. Gil +1
In this paper we present a computation of the thermally generated acceleration of the Cassini probe during its solar conjunction experiment, obtained from a model of the spacecraft…
A perturbative approach for the study of compatibility between nonminimally coupled gravity and Solar System experiments
Orfeu Bertolami, Riccardo March, Jorge Páramos
We develop a framework for constraining a certain class of theories of nonminimally coupled (NMC) gravity with Solar System observations.
