| Zusammenfassung |
| We are presenting characteristics of plasma and dust regions around Saturn’s moon Enceladus
with data from several instruments on board Cassini; the Langmuir probe and the electric
antenna connected to the wideband receiver of the radio and plasma wave science (RPWS)
instrument package and the magnetometer (MAG). Three main plasma and dust regions
around Enceladus have been observed. One is the plume which is filled with neutral gas,
plasma and charged dust. Then there is a dust tail on the downstream side of Enceladus and a
dusty edge region around the plume. In these regions, the dust is in equilibrium
with the surrounding plasma and gets charged by attracting free electrons. Sizes of
the smallest dust particles are found to be of 10Ânm in the dust tail region and the
plume edge whereas inside the plume even smaller particles of only 1Ânm in size
are inferred. The dust distribution follows a simple power law. The charged dust
also affects the Alfvén wings and they are asymmetric in the north south direction. |
