Influence of wall impacts on the Ulysses dust detector on understanding the interstellar dust flux

Krüger, H.; Grün, E.; Altobelli, N. +2 more

The Ulysses spacecraft orbits the Sun on a highly inclined orbit, and the impact ionization dust detector on board continuously measures interstellar dust grains with masses up to 10^-13kg, penetrating deep into the Solar System. The flow direction is close to the mean apex of the Sun's motion through the local interstellar cloud (LIC), …

Quasi-periodic emissions (15- 80 min) from the poles of Jupiter as a principal source of the large-scale high-latitude magnetopause boundary layer of energetic particle

Preka-Papadema, P.; Anagnostopoulos, G. C.; Karanikola, I. +2 more

In this study, we concentrate on the examination of the quasi-periodic behavior of 0.5-1.6 MeV(∼40-400 keV) protons (electrons) and of relativistic (>16 MeV) electrons, observed at Jupiter by two different experiments onboard Ulysses, the HI-SCALE and COSPIN, respectively, within the large-scale south duskside magnetopause boundary layer (MPBL)…

Comet Hyakutake (C/1996 B2): Spectacular disconnection event and the latitudinal structure of the solar wind

Brandt, J. C.; Snow, M.; Mikuz, H. +2 more

Images of comet Hyakutake (C/1996 B2) are analyzed in conjunction with solar wind data from spacecraft to determine the relationship between solar wind conditions and plasma tail morphology. The disconnection event (DE) on March 25, 1996 is analyzed with the aid of data from the IMP-8 and WIND Earth-orbiting spacecraft and the DE is found to be co…

On a systematic spectral variation of energetic ions in the Jovian outer magnetosphere: HI-SCALE/Ulysses observations

Sarris, E. T.; Anagnostopoulos, G. C.; Marhavilas, P. K.

An important finding of Ulysses flyby of Jupiter is the discovery of a large-scale energetic particle layer adjacent to the magnetopause. Previous studies discussed the particle flux and the anisotropy characteristics of this layer. This study examines the spectral characteristics of the large-scale magnetopause boundary layer of energetic particl…

Evidence for chaotic dynamics in the Jovian magnetosphere

Sarris, E. T.; Anagnostopoulos, G. C.; Pavlos, G. P. +2 more

In this paper, for the first time we examine the hypothesis of chaotic behaviour for the dynamics of the inner of Jupiter's magnetosphere as which is appeared in energetic populations. For this, we study geometrical and dynamical characteristics of Jovian energetic ion time series in the reconstructed phase space by using the SVD extended chaotic …
