Caption: Fig. 2.
Left: Radial (solid line) and vertical (dashed line) oscillations performed by the center of the torus after an impulsive radial perturbation at ﹩t=0﹩. Right: Fourier transforms of the radial (solid line) and vertical (dashed line) oscillations shown in the left panel. The two curves have been rescaled so as to fit on the same graph.
