We study stellar trajectories in a dominating central potential perturbed by an axisymmetric source of gravity. We aim this model to galactic nuclei where the motion of stars on the shortest time-scale is governed by gravity of a central supermassive black hole. The perturbation to its gravitational field is assumed to be due to an accretion disc or a gaseous torus. A hydrodynamical drag of the disc on the stellar trajectories is also considered. We discuss different observable consequences of the perturbed stellar trajectories. In particular, we examine to what degree the relativistic perihelion precession inhibits the effect of Kozai oscillations.
