# f(R) actions, cosmic acceleration and local tests of gravity

@article{Navarro2006fRAC, title={f(R) actions, cosmic acceleration and local tests of gravity}, author={Ignacio Navarro and Karel Van Acoleyen}, journal={Journal of Cosmology and Astroparticle Physics}, year={2006}, volume={2007}, pages={022 - 022} }

We study spherically symmetric solutions in f(R) theories and its compatibility with local tests of gravity. We start by clarifying the range of validity of the weak field expansion and show that, for many models proposed to address the dark energy problem, this expansion breaks down in realistic situations. This invalidates the conclusions of several papers that make inappropriate use of this expansion. For the stable models that modify gravity only at small curvatures we find that when the…

It is shown that the original version of this theory disagrees with solar system observations, and is equivalent to a scalar-tensor theory in which the scalar field kinetic energy term is absent from the action.
