Abstract: |
Nonlinear effects determining the amplitudes of unstable modes of oscillations in stellar modes are reviewed. The two basic processes - saturation of the driving mechanism and resonant mode coupling - are discussed within the framework of the amplitude equation formalism. There are difficult problems in the theory of multiple mode interaction that must be solved to make a prediction of amplitude spectra possible. The observed spectra for Delta Scu stars and other multiperiodic variables exhibit no simple pattern that would suggest a solution of the theoretical problems. |
