A linearized analysis is presented of the stability of a shell which accretes mass as it expands in a plasma under the push of the electromagnetic radiation trapped inside it. The interaction with the radiation is described in terms of a ponderomotive force and the shell dynamics is treated within the snowplow approximation. The mass accretion and the radiation expansion are shown to affect the stability of planar, cylindrical, and spherical shells differently.

Abstract
A linearized analysis is presented of the stability of a shell which accretes mass as it expands in a plasma under the push of the electromagnetic radiation trapped inside it. The interaction with the radiation is described in terms of a ponderomotive force and the shell dynamics is treated within the snowplow approximation. The mass accretion and the radiation expansion are shown to affect the stability of planar, cylindrical, and spherical shells differently.File in questo prodotto:
