Density Inhomogeneities

It is hypothesized that the observed clumping of plasma waves in type III sources in the solar wind is due to suppression of the linear stream-plasma interaction by density inhomogeneities of scale size comparable to the characteristic amplification length. Criteria are given for when such suppression should be important. The magnitude and scaling of density inhomogeneities in the 50–200 km range near 0.5 AU is estimated from interplanetary scintillation data. This information is used to construct model sources in which plasma waves are traced and amplified with random inhomogeneities to test the hypothesis. Significant clumping occurs for inhomogeneity scales of 50 and 100 km with inhomogeneity expectation values of 4.8×10−3 and 6.0×10−4, respectively, but not for 200 km scales. Further research is suggested to determine more completely the effects of density inhomogeneities in type III sources. Further details can be found in Smith, D.F., Sime, D. 1979, Astrophys. J., in press.

F Ring

ABSTRACTSaturn's broad E ring, the narrow G ring and the structured and apparently time variable F ring(s), contain many micron and sub-micron sized particles, which make up the “visible” component. These rings (or ring systems) are in direct contact with magnetospheric plasma. Fluctuations in the plasma density and/or mean energy, due to magnetospheric and solar wind processes, may induce stochastic charge variations on the dust particles, which in turn lead to an orbit perturbation and spatial diffusion. It is suggested that the extent of the E ring and the braided, kinky structure of certain portions of the F rings as well as possible time variations are a result of plasma induced electromagnetic perturbations and drag forces. The G ring, in this scenario, requires some form of shepherding and should be akin to the F ring in structure. Sputtering of micron-sized dust particles in the E ring by magnetospheric ions yields lifetimes of 102to 104years. This effect as well as the plasma induced transport processes require an active source for the E ring, probably Enceladus.
