      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
      In this paper, we compare the effects of different theories of gravitation on the apsidal motion of eccentric eclipsing detached binary stars. The comparison is performed by using the formalism of the post-Newtonian ...

    • Testing f(R)-Theories by Binary Pulsars 

      Autor: De Laurentis, Mariafelicia; De Martino, Ivan
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
      Using the Post-Keplerian parameters to obtain, in the Minkowskian limit we obtain constraints on f(R)-theories of gravity from the first time derivative of the orbital period of a sample of binary stars. In the approximation ...
