Fig. 5

Apsidal precession due to tidal distortion (solid red line) and GR effects (dotted blue line) in a system composed of a 1 M⊕ planet around a 0.08 M⊙ BD with initial a = 0.01 au and e = 0.1. In this example, the argument of periastron completes an orbit in ~14 750 yr when is affected by GR and in ~3060 yr when is affected by tidal distortion.
