Amplitudes of stochastically excited oscillations of models of ξ Hydrae (HR4450) are presented.The theoretical results are compared with the recent measurements by an international group of astronomers announced in the ESO press release 10/02.Using a stochastic excitation model we find fair agreement between estimated velocity amplitudes and the values quoted in the ESO press release.
