Journal ArticleDOI

Fritz M. Neubauer,Karl-Heinz Glassmeier,M. Pohl,Joachim Raeder,Mario H. Acuña,L. F. Burlaga,Norman F. Ness,G. Musmann,F. Mariani,Max K. Wallis,E. Ungstrup,H. U. Schmidt +11 more
TL;DR: The Giotto magnetometer experiment at comet Halley has for the first time provided magnetic field measurements in all the important spatial regions characterizing the front-side interaction between the solar-wind magnetoplasma and a cometary atmosphere.
Book ChapterDOI

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

TL;DR: In this paper, the density and the mass spectrum of the dust near comet Halley have been measured by the Giotto space probe's dust impact detection system, showing depletion in small and intermediate masses; at about 600 km from the nucleus, however, the dust activity rises and the spectrum is dominated by larger masses.

TL;DR: The three-dimensional positive ion analyzer aboard the Giotto spacecraft has been used to study the interaction between protons and alpha-particles in the solar wind and positive ions from comet Halley as discussed by the authors.
Journal ArticleDOI
Radiogenic melting of primordial comet interiors
TL;DR: In this article, a central, low pressure vapour-droplet mixture is described, which is conceived to be retained within an ice shell, and providing a potentially hospitable environment for elementary life forms.
