Energetic electron asymmetries at Mars: ASPERA-3 observations
Barabash, S.; Lundin, R.; Winningham, J. D. +7 more
Energetic electron fluxes from more than two years of ASPERA-3 observations are organized in different coordinate systems for the investigation of asymmetries in the global dynamics of the Martian magnetosphere. A clear asymmetry is found in the distribution of high-flux events with respect to the solar wind convective electric field ( Esw
The magnetic field near Mars: A comparison between a hybrid model, Mars Global Surveyor and Mars Express observations
Kallio, E.; Fedorov, A.; Janhunen, P. +5 more
Mars Express (MEX) does not carry its own magnetometer which complicates interpretation of ASPERA-3/MEX ion measurements. The direction of the interplanetary magnetic field (IMF) is especially important because it, among other things, determines the direction of the convective electric field and orientation of the cross tail current sheet and tail…
Analysis of the H + ring velocity distribution function near the Martian and Venusian bow shocks by an analytical model
Kallio, E.; Yamauchi, M.; Frilund, H.
We have studied the H + velocity distribution function at Mars and Venus near the bow shock both in the solar wind and in the magnetosheath by a simple analytical one-dimensional model. We found that over half of the ions in the ring velocity distribution which moved towards the magnetosheath were scattered back into the bow shock. The …
