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 (J_φ) distribution in radial (ρ), height (z), and local time (LT) dimensions. After binning the in-situ magnetic field data into 2 R_J × 2 R_J × 3 h (R_J is the …
