Abstract
By using the Cowling approximation, quasi-radial modes of rotating general relativistic stars are computed along equilibrium sequences from non-rotati ng to maximally rotating models. The eigenfrequencies of these modes are de creasing functions of the rotational frequency. The eigenfrequency curve of each mode as a function of the rotational frequency has discontinuities, w hich arise from the avoided crossing with other curves of axisymmetric mode s.
