We have analysed and attempted to classify the acoustic ray patterns in stars whose equilibrium figure is globally deformed. We discuss here the effect of distortions of ellipsoidal and pear-shaped structure. Under ellipsoidal symmetry all ray patterns remain ‘regular’. For arbitrarily small pear-shaped deformations our numerical results indicate the occurrence of ‘chaotic’ ray patterns arising out of the unstable longest diameter ray. These chaotic rays cover the whole configuration space.
