Research Interests:

Studies of waves and instabilities in magnetospheric plasma and in solar wind plasma; physical processes of reconnection and substorm. Previous work involved analysis of ground magnetic field data and of data from multi-instruments from various spacecraft, including DE-1, ISEE-1 and 2, AMPTE/IRM and CCE, and most recently, Ulysses.

Ulysses/URAP Research at University of Minnesota

Research conducted in the University of Minnesota using URAP data has mostly involved the study of in situ plasma waves detected by the plasma frequency reciever (PFR), the wave form analizer (WFA) and the fast envelope sampler (FES). The URAP plasma wave instrument is unique for measuring low frequency waves because the spin axis of the spacecraft is always nearly toward the Sun and thus there is less photoelectron effect; and the measurements are extended to frequencies as low as a fraction of Hertzs. These advantages have been utilized to make a number of important observations of very low frequency (VLF) plasma waves in the solar wind, as well as in the Jovian magnetosphere.

Some of the significant results from the Minnesota group, obtained during the primary mission, and in the first few years of Ulysses Solar Maximum Mission, are summarized here.
