TL;DR
This study analyzes magnetic fluctuations in Venus's magnetosheath, terminator, and wake, revealing distinct turbulence characteristics and statistical properties across different regions of Venus's induced magnetosphere.
Contribution
It provides the first statistical analysis of magnetic fluctuations in Venus's terminator and wake regions, identifying turbulence patterns and non-Gaussian statistics.
Findings
1/f fluctuations in the magnetosheath
Large-scale structures near the terminator
Developed turbulence in the wake
Abstract
Recent research has shown that distinct physical regions in the Venusian induced magnetosphere are recognizable from the variations of strength and of wave/fluctuation activity of the magnetic field. In this paper the statistical properties of magnetic fluctuations are investigated in the Venusian magnetosheath, terminator, and wake regions. The latter two regions were not visited by previous missions. We found 1/f fluctuations in the magnetosheath, large-scale structures near the terminator and more developed turbulence further downstream in the wake. Location independent short-tailed non-Gaussian statistics was observed.
