Langmuir Wave Activity: Comparing the Ulysses Solar Minimum and Solar Maximum Orbits
We examine the occurrence and intensity of Langmuir wave activity (electrostatic waves at the electron plasma frequency) during the solar minimum and solar maximum orbits of Ulysses. At high latitudes during the ...

Ion Acoustic Waves in the Heliosphere
Observations of ion acoustic waves in the solar wind during the first and second orbit of the Ulysses spacecraft are presented. The observations show variations of the wave activity with the heliolatitude and wit...

In Situ Wave Phenomena Associated with Magnetic Clouds and Other Ejecta
We present Ulysses Unified Radio and Plasma Wave (URAP) observations of ion-acoustic waves associated with magnetic clouds and ejecta. The peak intensities of these waves, which usually occur inside CMEs when T ...
