主　　题：Binary pulsars f ( R ) -gravity post-Keplerian formalism 

摘      要：We develop the parameterized post-Keplerian approach for class of analytic f ( R ) -gravity models. Using the double binary pulsar system PSR J0737-3039 data we obtain restrictions on the parameters of this class of f ( R ) -models and show that f ( R ) -gravity is not ruled out by the observations in strong field regime. The additional and more strong corresponding restriction is extracted from solar system data.
