Abstract

In a gravitationally stratified atmosphere, a pulse followed by eigenoscilla-tions of the medium at the cutoff period may show motions that are better able than a model based on short-period waves to reproduce intensity enhancements and frequency shifts in the K line. In order to examine this question we study pulse propagation in an isothermal medium.
