Late Dust Pedestal Rise Mechanisms
Abstract
The mechanism of buoyant rise is found to be quantitatively consistent with readily available photographic data on the late dust pedestal of events Wasp Prime and Climax. The term 'late' refers to times after the rapid initial pedestal rise, and can be conveniently defined in terms of Liner's model. One implication of buoyancy as a driving force for late pedestal rise is that the average bulk density in most or all of the dust pedestal is small compared to air density, that is, small compared to 10-3 g/cm3. A number of mechanisms other than buoyancy were investigated as causes for the late rise with discouraging results; These mechanisms are listed along with a brief description of the reasons each is untenable.
