Abstract

The overstability of sound waves in a polytropic atmosphere is examined for disturbances of arbitrary optical thickness. It is concluded that the Cowling-Spiegel mechanism can operate in the solar convective zone, although the κ-mechanism is predominantly responsible for the observed five-minute oscillations.
