The dust distribution within the inner coma of comet P/Halley 1982i: encounter by Giotto's impact detectors.
J. A. M. McDonnell,W. M. Alexander,W. M. Burton,E. Bussoletti,G. C. Evans,S. T. Evans,J. G. Firth,Réjean Grard,Simon F. Green,Eberhard Grün,Martha S. Hanner,David W. Hughes,Eduard Igenbergs,Jochen Kissel,H. Kuczera,Bertil Anders Lindblad,Yves Langevin,J.C. Mandeville,S. Nappo,G. S. Pankiewicz,C. H. Perry,Gerhard Schwehm,Z. Sekanina,T. J. Stevenson,R. F. Turner,U. Weishaupt,Max K. Wallis,John C. Zarnecki +27 more
TL;DR: Data at large masses recently analysed from the DIDSY data set show clear evidence of a decrease in the mass distribution index at these masses within the coma, and it is shown that such a value of the mass index can provide sufficient mass for consistency with the observed deceleration.
Journal ArticleDOI
In situ exploration of the dusty coma of comet P/Halley at Giotto's encounter: Flux rates and time profiles from 10−19kg To 10−5kg
J. A. M. McDonnell,Simon F. Green,Eberhard Grün,Jochen Kissel,S. Nappo,G. S. Pankiewicz,C. H. Perry +6 more
TL;DR: Flux rates and time profiles from the Giotto DIDSY and PIA experiments are presented in the light of more refined data analysis and increased data coverage in this article, where the methods of data analysis for both experiments are explained, together with relevant behaviour of their in-flight performance.
Giotto's Dust Impact Detection System (DIDSY) and Particulate Impact Analyzer (PIA): Interim assessment of the dust distribution and properties within the coma

Journal ArticleDOI
The composition and plasma signature of a large dust impact on the giotto spacecraft
Richard M. Goldstein,Bruce E. Goldstein,Hans Balsiger,Andrew J. Coates,W. Curdt,H. U. Keller,Fritz M. Neubauer,C. H. Perry,John C. Zarnecki +8 more
TL;DR: In this paper, the authors combine direct measurements of the composition and dynamics of a dust impact plasma cloud, the dust particle mass and the location of the impact on the Giotto spacecraft.
A possible explanation for the inconsistency between the Giotto grain mass distribution and ground-based observations
TL;DR: In this article, it was concluded that Giotto DIDSY and GRE data represent observations of dust originating from a narrow track along the nucleus, and that the actual size distribution that should be used for modeling of the whole coma should not include the large mass excess actually observed by Giotto.
