The growing availability of increasingly accurate data on transiting exoplanets suggests the possibility of using these systems as possible testbeds for modified models of gravity. In particular, we suggest that the post-Keplerian (pK) dynamical effects from the perturbations of the Newtonian potential falling off as the square or the cube of the distance from the mass of the host star break the degeneracy of the anomalistic, draconitic and sidereal periods. The latter are characteristic temporal intervals in the motion of a binary system, and all coincide in the purely Keplerian case. We work out their analytical expressions in presence of the aforementioned perturbations to yield preliminary insights on the potential of the method proposed for constraining the modified models of gravity considered. A comparison with other results existing in the literature is made.

用系外行星探测牛顿势的 ar−n 修正

关于凌日系外行星的越来越准确的数据越来越多，这表明使用这些系统作为修改重力模型的可能试验台的可能性。特别是，我们建议，牛顿势的扰动引起的后开普勒 (pK) 动力学效应随着距主星质量距离的平方或立方而下降，打破了异常、龙质和恒星的简并性。期间。后者是双星系统运动中的特征时间间隔，并且在纯开普勒情况下都是一致的。我们在存在上述扰动的情况下计算出它们的分析表达式，以初步了解所提出的用于约束所考虑的修正重力模型的方法的潜力。
