摘要：

The excitation of the possible non-radial oscillations of supergiant stars is still a puzzle. We perform a non-radial, non-adiabatic stability analysis on a series of stellar envelope models of varying mass. A number of excited low-order modes is found. The modes are excited by mode interaction which is found in luminous stars with extended envelopes. Observational consequences are discussed.
