Probing Models of Extended Gravity using Gravity Probe B and LARES experiments
arXiv:1410.8316 · doi:10.1103/PhysRevD.91.044012
Abstract
We consider models of Extended Gravity and in particular, generic models containing scalar-tensor and higher-order curvature terms, as well as a model derived from noncommutative spectral geometry. Studying, in the weak-field approximation, the geodesic and Lense-Thirring processions, we impose constraints on the free parameters of such models by using the recent experimental results of the Gravity Probe B and LARES satellites.
