The DESTINY
A novel methodology to estimate pre-atmospheric dynamical conditions of small meteoroids
Weryk, Robert; Janches, Diego; Stober, Gunter +5 more
Recent observations using the Wind and Ulysses spacecrafts and the Solar Occultation For Ice Experiment (SOFIE) during the period between 2007 and 2020 indicate a total cosmic dust influx at Earth ranging from 22 to 32 tonnes per day. Much is still unclear about the formation, evolution, and propagation of this cosmic dust throughout our Solar Sys…
Impact ionization dust detection with compact, hollow and fluffy dust analogs
Srama, R.; Pommerol, A.; Hornung, K. +14 more
Impact ionization of high-velocity cosmic dust particles has been used as a basic principle for dust detectors in space for many decades. It has provided optimum means to gain insight into the dust environment in the solar system. The Ulysses Dust Detector System provided for the first time impact ionization-based detection of interstellar dust (I…
An empirical model of the current sheet in Jupiter's magnetosphere
Zhang, Lei; Wang, Jian-zhao; Huo, Zhuo-xi
Based on the Magnetometer data from the Galileo and Juno mission, we construct an analytical ring current model that provides the azimuthal current (Jφ) distribution in radial (ρ), height (z), and local time (LT) dimensions. After binning the in-situ magnetic field data into 2 RJ × 2 RJ × 3 h (RJ is the …
Science data visualization in planetary and heliospheric contexts with 3DView
André, N.; Budnik, E.; Pitout, F. +21 more
We present a 3D orbit viewer application capable of displaying science data. 3DView, a web tool designed by the French Plasma Physics Data Center (CDPP) for the planetology and heliophysics community, has extended functionalities to render space physics data (observations and models alike) in their original 3D context. Time series, vectors, dynami…
Survey of caveats in low-energy particle measurements: Ulysses/HI-SCALE and ACE/EPAM Instruments
Malandraki, O. E.; Anagnostopoulos, G. C.; Marhavilas, P. K.
"Heliosphere Instrument for Spectra, Composition, and Anisotropy at Low Energies" (HI-SCALE) onboard the ULYSSES spacecraft, and "Electron, Proton, and Alpha Monitor" (EPAM) onboard the ACE spacecraft, are very similar instruments and were designed to make measurements of ions and electrons over a broad range of energy and intensity. The ions (E
Dense molecular cloud cores as a source of micrometer-sized grains in galaxies
Li, Zhi-Yun; Hirashita, Hiroyuki; Nozawa, Takaya +2 more
Coreshine in dense molecular cloud cores (dense cores) is interpreted as evidence for micrometer-sized grains (referred to as very large grains, VLGs). VLGs may have a significant influence on the total dust amount and the extinction curve. We estimate the total abundance of VLGs in the Galaxy, assuming that dense cores are the site of VLG formati…
A multifractal approach applied to the magnetic field turbulence in Jupiter's magnetosheath
Bolzan, M. J. A.; Echer, E.
We studied the magnetic field turbulence in Jupiter's magnetosheath during the Ulysses inbound trajectory in 1992. This analysis was conducted using nonlinear techniques such as kurtosis, probability density functions, multifractal approach and wavelet analysis. The results from the PDFs and kurtosis analysis, for each magnetic field component, sh…
The ~10 hour modulation of the relativistic electron spectrum as a result of the periodic motion of the Jovian outer magnetosphere layer: Ulysses observations
Anagnostopoulos, G. C.; Karanikola, I.; Marhavilas, P. K.
We analyze relativistic (E>3 MeV) electron observations during the dayside inbound trajectory of Ulysses (day 33 to day 38, 1992) in the Jovian magnetosphere and we demonstrate that the continuous presence of a relativistic electron layer at higher north latitudes (Ulysses reached ~40° lat. during closest approach the planet). In particular, we…
The large-scale energetic ion layer in the high latitude Jovian magnetosphere as revealed by ULYSSES/HI-SCALE cross-field intensity-gradient measurements
Sarris, E. T.; Anagnostopoulos, G. C.; Karanikola, I. +1 more
ULYSSES investigated the high latitude Jovian magnetosphere for a second time, after Pioneer 11 mission, and gave us the opportunity to search the structure and the dynamics of this giant magnetosphere above the magnetodisc. Kivelson and Williams (1976) and Kennel and Coroniti (1979) reported that Pioneer 11 observed energetic particle intensities…
