摘要：

We consider dynamical effects of additional perturbative forces due to the non-point-mass nature of stars and planets: effects such as quadrupolar distortion and tidal friction in the systems of exoplanets. It is shown that one should not neglect these forces while modeling the dynamics of planetary systems, especially taking into account the undefined real masses of the planets due to unknown orbital inclinations and the unsatisfactory application of Keplerian fits to the radial velocity data in multiple planetary systems.
