Abstract
The dynamics of clumps observed in planetary nebulae are considered. T he possibility that SiO maser spots in evolved stars and the planetary nebula clumps are formed by the Parker instability behind shocks in p ulsating stars' atmospheres is raised. Molecular observations of the c lumps are suggested. The effects of the ablation of clumps on the glob al flow structure of a more tenuous plasma in which they are embedded are reviewed.
