论文摘要

我们开发了用于混合度量帕拉蒂尼$ f(r)$ - 重力的参数化后的骑术后形式主义。我们在四个PPK参数的Generel Ecentric Case中获得了分析表达式:$ \dotΩ$,$ \ dot p _ {\ rm b} $,$ r $和$ s $。使用PSR J0737-3039和PSR J1903+0327的观察数据,我们对混合F(R)重力的参数施加了限制,并表明该理论并未被强场策略中的观察结果所排除。此外,我们还获得了系统组件质量的预测,发现所考虑的天体物理对象将比GR重。

We developed the parameterized post-Keplerian formalism for hybrid metric-Palatini $f(R)$-gravity. We obtained analytical expressions in the generel eccentric case for four PPK parameters: $\dotω$, $\dot P_{\rm b}$, $r$ and $s$. Using observational data of PSR J0737-3039 and PSR J1903+0327 we imposed restrictions on the parameters of hybrid f(R)-gravity and showed that this theory is not ruled out by the observations in strong field regime. In addition we obtained predictions for masses of systems components and found that considered astrophysical objects will be heavier than in GR.
