Example of a buckling orbit. The orbit is plotted in different colors in three time periods: before, during, and after buckling (from the left to the right panel) and in two projections: in the face-on and edge-on view (the top and bottom row, respectively). After buckling the star follows a regular, periodic, pretzel-like orbit with frequency ratio f_{z,  after}/f_{x,  after} = 7/4, that is it completes four oscillations in x for every seven oscillations in z.
