Journal ArticleDOI
Cassini between Earth and asteroid belt: first in-situ charge measurements of interplanetary grains
Sascha Kempf,Ralf Srama,Nicolas Altobelli,S. Auer,V. Tschernjawski,J. Bradley,M. Burton,Stefan Helfert,T. V. Johnson,Harald Krüger,Georg Moragas-Klostermeyer,Eberhard Grün +11 more
TL;DR: In this article, the authors reported the first successful in-situ measurement of charged interplanetary dust grains by CDA and identified 6 impacts whose QP signals show a clear feature caused by charged grains, corresponding to Qd between 1.3 and 5.4 fC.
Journal ArticleDOI
Cold dust around nearby stars (DUNES). First results: A resolved exo-Kuiper belt around the solar-like star zeta^2 Ret
Carlos Eiroa,Davide Fedele,Jesús E. Maldonado,B. M. González-García,J. Rodmann,Ana M. Heras,Göran Pilbratt,J.-Ch. Augereau,A. Mora,Benjamin Montesinos,David R. Ardila,G. Bryden,René Liseau,K. R.

TL;DR: The first far-IR observations of the solar-type stars delta Pav, HR 8501, 51 Peg and zeta^2 Ret were presented in this article. But these observations were taken within the context of the DUNES Herschel Open Time Key Programme (OTKP).
Journal ArticleDOI
A 2 MV Van de Graaff accelerator as a tool for planetary and impact physics research.
Anna Mocker,S. Bugiel,S. Auer,Günter Baust,Andrew Colette,K. Drake,K. Fiege,Eberhard Grün,Frieder Heckmann,Stefan Helfert,Jonathan Hillier,Sascha Kempf,G. Matt,Tobias Mellert,Tobin Munsat,K. Otto,Frank Postberg,Hans-Peter Röser,Anthony Shu,Zoltan Sternovsky,Ralf Srama +20 more
TL;DR: This work accelerates charged micron and submicron-sized dust particles to speeds up to 80 km s(-1) in the laboratory, enabling the controlled investigation of hypervelocity impact phenomena across a hitherto unobtainable range of impact parameters.
Journal ArticleDOI
Three years of Galileo dust data
Eberhard Grün,M. Baguhl,N. Divine,H. Fechtig,Douglas P. Hamilton,Martha S. Hanner,Jochen Kissel,Bertil Anders Lindblad,D. Linkert,G. Linkert,Ingrid Mann,J. A. M. McDonnell,Gregor E. Morfill,C. Polanskey,R. Riemann,Gerhard Schwehm,N. Siddique,P. Staubach,H. A. Zook +18 more
TL;DR: The impact rate varied from 0.2 to 2 impacts per day depending on the heliocentric distance and direction of spacecraft motion with respect to the interplanetary dust cloud.
Journal ArticleDOI
Composition of jovian dust stream particles
Frank Postberg,Sascha Kempf,Ralf Srama,Simon F. Green,Jon K. Hillier,Neil McBride,Eberhard Grün +6 more
TL;DR: In this paper, the mass spectra of jovian stream particles were used to determine the chemical composition of particles, and the results imply that the vast majority (>95%) of the observed stream particles originate from the volcanic active jovians satellite Io from where they are sprinkled out far into the Solar System.
