Saturn kilometric radiation as a monitor for the solar wind?
Dougherty, M. K.; Kurth, W. S.; McComas, D. J. +9 more
Since the Voyager mission it is known that Saturn Kilometric Radiation (SKR) is strongly influenced by external forces, i.e., the solar wind and in particular the solar wind ram pressure. Recent studies using Cassini data essentially confirmed these findings for particular periods during the first Cassini orbit of Saturn. The data coverage of SKR …
Solar wind structure in the outer heliosphere
Liu, Y.; Wang, C.; Richardson, J. D.
A solar wind parcel evolves as it moves outward, interacting with the solar wind plasma ahead of and behind it and with the interstellar neutrals. This structure varies over a solar cycle as the latitudinal speed profile and current sheet tilt change. We model the evolution of the solar wind with distance, using inner heliosphere data to predict p…
Density of discontinuities in the heliosphere
Balogh, A.; ErdőS, G.
The spatial distribution of MHD discontinuities in the solar wind has been studied, based on the long time observations by the magnetometer onboard Ulysses. We emphasize the critical importance of the method whereby events are selected; some previous work is critically reviewed in this respect. Our analysis supports earlier observations that the d…
