Testing <em>f(R)</em>-Theories by Binary Pulsars
Using the Post-Keplerian parameters to obtain, in the Minkowskian limit we obtain constraints on <em>f(R)</em>-theories of gravity from the first time derivative of the orbital period of a sample of binary stars. In the approximation in which the theory is Taylor expandable, we can estim...

| description | Using the Post-Keplerian parameters to obtain, in the Minkowskian limit we obtain constraints on <em>f(R)</em>-theories of gravity from the first time derivative of the orbital period of a sample of binary stars. In the approximation in which the theory is Taylor expandable, we can estimate the parameters of an an analytic <em>f(R)</em>-theory, and fullling the gap between the General Relativity prediction and the one cames from observation, we show that the theory is not ruled out. |
