Deupree, R. G. ; Hodson, S. W. Abstract Based on two-dimensional hydrodynamical calculations, it is suggested that the origin of the alternating amplitudes of RV Tauri variables lies in time-dependent convection. Calculations indicate that, under certain conditions, large-amplitude convective motion may get damped out every other period. The primary condition appears to be that the convective velocities be large (very near the sound speed). Such is likely the case for such luminous and cool stars as the RV Tauri variables.
