Jovian Dust Streams: A monitor of Io’s volcanic plume activity
Streams of high speed dust particles originate from Jupiter’s innermost Galilean moon Io. After release from Io, the particles collect electric charges in the Io plasma torus, gain energy from the co-rotating electric field of Jupiter’s magnetosphere, and leave the Jovian system into interplanetary space with escape speeds over 200 km s. Galileo, which was the first orbiter spacecraft of Jupite...
متن کاملJovian dust streams: Probes of the Io plasma torus
Jupiter was discovered to be a source of high speed dust particles by the Ulysses spacecraft in 1992. These dust particles originate from the volcanic plumes on Io. They collect electrostatic charges from the plasma environment, gain energy from the co-rotating electric field of the magnetosphere, and leave Jupiter with escape speeds over 200 kms. The dust streams were also observed by the Gali...
متن کاملCharacterization of Jovian Plasma-Embedded Dust Particles
As the data from space missions and laboratories improve, a research domain combining plasmas and charged dust is gaining in prominence. Our solar system provides many natural laboratories such as planetary rings, comet comae and tails, ejecta clouds around moons and asteroids, and Earth’s noctilucent clouds for which to closely study plasma-embedded cosmic dust. One natural laboratory to study...
متن کاملDust en-route to Jupiter and the Galilean satellites
Spacecraft investigations during the last ten years have vastly improved our knowledge about dust in the Jovian system. All Galilean satellites, and probably all smaller satellites as well, are sources of dust in the Jovian system. In-situ measurements with the dust detectors on board the Ulysses and Galileo spacecraft have for the first time demonstrated the electromagnetic interaction of char...
متن کاملObservations of nucleation of new particles in a volcanic plume.
Volcanic eruptions caused major weather and climatic changes on timescales ranging from hours to centuries in the past. Volcanic particles are injected in the atmosphere both as primary particles rapidly deposited due to their large sizes on time scales of minutes to a few weeks in the troposphere, and secondary particles mainly derived from the oxidation of sulfur dioxide. These particles are ...
