A rough-surface scattering function for Titan radar studies
Campbell, Bruce A.
Numerous studies show a relationship between radar backscattering and surface roughness. While estimating the statistical properties of small-scale topography is of particular interest for geologic analysis of Cassini radar data, there is no analytic description of radar scattering over a wide range of incidence angles and roughness. This paper pr…
Banana-polarized solitons in anisotropic plasmas related to Ulysses observations
Dubinin, E.; Sauer, K.; Baumgärtel, K. +1 more
Localized magnetic compressions associated with a rotation in the magnetic field direction have recently been reported after surveying Ulysses high-resolution data. Although the observed structures have similarities to usual Hall-MHD solitons, the banana-type polarization of the described rare events is a decisive signature which counts against su…
Possible eigenmode trapping in density enhancements in Saturn's inner magnetosphere
Gurnett, D. A.; Menietti, J. D.; Yoon, P. H.
We report a re-examination of observations of radio waves and banded fine structure observed by Cassini in the Saturn inner magnetosphere. These emissions have been identified in the past as Z-mode emission from possible density cavities along the inner edge of the Saturn plasma torus. A careful examination of the emission fine structure in a regi…
Plasma sheet fine structure at high latitude
Rème, H.; Kistler, L.; Lennartsson, O. W.
High-resolution ion observations made in recent years, by the TIMAS instrument on the Polar satellite and other instruments, reveal a dynamic and finely structured plasma sheet, at least at high latitude. This study invokes multipoint Cluster observations with the CIS CODIF instruments (ion composition and distribution function) to determine wheth…
