Research includes ongoing studies of Io and Io Torus, particularly time-variable phenomena. These programs also focus on aurorae on gas giants. Searches are underway for planetary bodies the orbit of Pluto.
Cometary research emphasizes the interaction of bright comets (such as Halley) with the solar wind and interplanetary magnetic field, interpreting ion structures in the comet seen in wide-angle images of the tail, and narrow-field images of the ion coma and spectra. We are also interested in what solar-wind/IMF conditions initiate the formation of transient structures in the cometary tails, where in the comet the seat of the initial disturbance resides (e.g., sunward comma, inner ion tail), and what specific instability mechanism is involved. Structures important to probe in this manner are disconnection events, folding ion tail rays, and propagating helical waves.
