Imaging the Dust Trail and Neckline of 67P/Churyumov-Gerasimenko
Agarwal, Jessica; Boehnhardt, Hermann; Gruen, Eberhard
We report on the results of nearly 10 hours of integration of the dust trail and neckline of comet 67P/Churyumov- Gerasimenko (67P henceforth) using the Wide Field Imager at the ESO/MPG 2.2m telescope in La Silla. The data was obtained in April 2004 when the comet was at a heliocentric distance of 4.7 AU outbound. 67P is the target of the Rosetta …
Solar Wind Modulation of Jupiter Dust Stream Detection
Flandes, A.; Krueger, H.
During late 2002 and mid 2005, the Ulysses spacecraft approached Jupiter ( 0.8 AU at its closest distance) and detected 28 new Jovian dust particle streams. The tiny positively charged dust grains ( 10 nm) in the streams are accelerated away from Jupiter by its corotational electric field to very high speeds (greater than 200 km s^{-1}). Data indi…
Cassini Cosmic Dust Analyser: Composition of Dust at Saturn
Kempf, S.; Postberg, F.; Srama, R. +6 more
We discuss issues involved with interpreting time-of-flight mass spectra (TOFMS) obtained by the Chemical Analyser subsystem of the Cassini Cosmic Dust Analyser (CDA). We use an in-house ion dynamics code specifically written for CDA which helps us to understand and constrain the initial impact plasma ion kinetic energy and angular distributions. …
Dust Measurements During Ulysses' 2nd Jupiter Encounter
Gruen, E.; Krueger, H.
In 2004 the Ulysses spacecraft had its second flyby at Jupiter at 0.8 AU from the planet. 28 dust streams emanating from the jovian system were identified over a 26- month period while the spacecraft was within 4 AU of the planet, and the dust instrument was operating, scanning jovigraphic latitudes from +75 degrees to -25 degrees . From late 2002…
Dust in Planetary Systems
Krueger, H.; Graps, A.
The workshop 'Dust in Planetary Systems' was held in Kauai'i/Hawaii from September 26 to 30, 2005, following the tradition of holding meetings in the field of Interplanetary Dust Research at regular intervals of a few years. The series of meetings started in Honolulu, Hawaii (USA) in 1967, followed by Heidelberg (Germany) in 1975, Ottawa (Canada) …
