给出了ξHydrae(HR4450)模型的随机激励振动幅值。理论结果与一个国际天文学家小组最近在ESO新闻稿10/02中公布的测量结果进行了比较。使用随机激励模型，我们发现估计的速度幅度与ESO新闻稿中引用的值相当吻合。
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.
