摘要: We consider some models of f(R) gravity that can be used to describe, in a suitable weak-field limit, the gravitational field Sun. Using perturbative approach, we focus on impact modifications field, due non-linearity Lagrangian, have Solar System dynamics. compare theoretical predictions for precession longitude pericentre $\varpi$ test particle with corrections standard Newtonian-Einsteinian precessions longitudes perihelia planets recently estimated by E.V. Pitjeva fitting large data sets various versions EPM ephemerides.
