| Zusammenfassung |
| On December 30, 2000, the Cassini-Huygens spacecraft flew by Jupiter at a distance of 137
RJ (Jupiter radius, 71 400 km). Six months before the closest approach, when
the spacecraft was about 1 AU (astronomical unit) away from Jupiter, the Cassini
dust detector started to register impacts of fast (~ 200 km/s) and tiny (~ 10 nm)
grains, so-called stream particles. In contrast to the dust detection of the Galileo and
Ulysses spacecrafts, the Cassini instrument observed a contiuous flux of stream
particles coming from the Cassini-Jupiter line-of-sight. Based on the CDA data
and structure of the interplanetary field, we provide quantitative constrains on the
physical properties of Jovian stream particles and explain the differences between
the stream particle observations by the Ulysses, Galileo, and Cassini instruments. |
