Solar Wind Magnetic Field Bending of Jovian Dust Trajectories.
Science, 274, 1501-1503.
From September 1991 to October 1992, the cosmic dust detector on the
Ulysses spacecraft recorded 11 short bursts, or streams, of
dust. These dust grains emanated from the jovian system and their
trajectories were strongly affected by solar wind magnetic field
forces. Analyses of the on-board measurements of these fields, and of
stream approach directions, show that stream-associated dust grain
masses are of the order of 10^{-18} gram and dust grain velocities
exceed 200 kilometers per second. These masses and velocities are,
respectively, about 1000 times less massive and 5 to 10 times faster
than earlier reported.
