  We numerically analyze the impact of a single Rydberg electron onto a
Bose-Einstein condensate. Both $S-$ and $D-$ Rydberg states are studied. The
radial size of $S-$ and $D-$states are comparable, hence the only difference is
due to the angular dependence of the wavefunctions. We find the atom losses in
the condensate after the excitation of a sequence of Rydberg atoms.
Additionally, we investigate the mechanical effect in which the Rydberg atoms
force the condensate to oscillate. Our numerical analysis is based on the
classical fields approximation. Finally, we compare numerical results to
experimental data.
