Testing f(R) theories using the first time derivative of the orbital period of the binary pulsars.

DE LAURENTIS M. and DE MARTINO I.

Abstract (from CDS):

In this paper, we use one of the post-Keplerian parameters to obtain constraints on f(R) theories of gravity. Using the Minkowskian limit, we compute the prediction of f(R) theories on the first time derivative of the orbital period of a sample of binary stars, and we use our theoretical results to perform a comparison with the observed one. Selecting a sample of relativistic binary systems, we estimate the parameters of analytic f(R) gravity. We find that the theory is not ruled out if we consider only the double-neutron star systems, and in this case we can cover the existing gap between the general relativity prediction and the observed data.
