Statistical study of low-frequency magnetic field fluctuations near Venus under the different interplanetary magnetic field orientations

Zhang, T. L.; Wang, C.; Baumjohann, W. +4 more

The magnetic field fluctuations near Venus are investigated in the frequency range 0.03-0.3 Hz on the basis of the measurements observed by Venus Express from April 2006 to December 2008. The data are sorted by the angle between interplanetary magnetic field (IMF) and solar wind flow. The spatial distributions of fluctuation properties under the d…

Venusian bow shock as seen by the ASPERA-4 ion instrument on Venus Express

Coates, A. J.; Kallio, E.; Schmidt, W. +40 more

The Analyzer of Space Plasmas and Energetic Atoms (ASPERA-4) instrument on Venus Express is used to determine bow shock position at Venus using ion data alone, using data recorded during a solar minimum from the Ion Mass Analyzer (IMA) which is part of the ASPERA-4 package. Previous models constructed from solar minimum data using Venus Express, P…
