Implications of non-analytical f(R) gravity at Solar-System scales
arXiv:0807.4428 · doi:10.1088/0264-9381/26/4/045014
Abstract
We motivate and analyze the weak-field limit of a non-analytical Lagrangian for the gravitational field. After investigating the parameter space of the model, we impose constraints on the parameters characterizing this class of theories imposed by Solar-System data, i.e. we establish the validity range where this solution applies and refine the constraints by the comparison with planetary orbits. As a result, we claim that this class of models is viable within different astrophysical scales.
