Query: Solar System constraints to nonminimally coupled gravity   We extend the analysis of Chiba, Smith and Erickcek \cite{CSE} of Solar
System constraints on $f(R)$ gravity to a class of nonminimally coupled (NMC)
theories of gravity. These generalize $f(R)$ theories by replacing the action
functional of General Relativity (GR) with a more general form involving two
functions $f^1(R)$ and $f^2(R)$ of the Ricci scalar curvature $R$. While the
function $f^1(R)$ is a nonlinear term in the action, analogous to $f(R)$
gravity, the function $f^2(R)$ yields a NMC between the matter Lagrangian
density $\LL_m$ and the scalar curvature. The developed method allows for
obtaining constraints on the admissible classes of functions $f^1(R)$ and
$f^2(R)$, by requiring that predictions of NMC gravity are compatible with
Solar System tests of gravity. We apply this method to a NMC model which
accounts for the observed accelerated expansion of the Universe.
