The spacecraft wake: Interference with electric field observations and a possibility to detect cold ions

M. André, A. I. Eriksson, Yu. V. Khotyaintsev +1

Wakes behind spacecraft caused by supersonic drifting positive ions are common in plasmas and disturb in situ measurements. We review the impact of wakes on observations by the Ele…

Plasma densities, flow and Solar EUV flux at comet 67P - A cross-calibration approach

F. L. Johansson, A. I. Eriksson, E. Vigren +7

During its two-year mission at comet 67P, Rosetta nearly continuously monitored the inner coma plasma environment for gas production rates varying over three orders of magnitude, a…

Kinetic Electrostatic Waves and their Association with Current Structures in the Solar Wind

D. B. Graham, Yu. V. Khotyaintsev, A. Vaivads +21

A variety of kinetic waves develop in the solar wind. The relationship between these waves and larger-scale structures, such as current sheets and ongoing turbulence remain a topic…

Density Fluctuations Associated with Turbulence and Waves: First Observations by Solar Orbiter

Yu. V. Khotyaintsev, D. B. Graham, A. Vaivads +21

We use the plasma density based on measurements of the probe-to-spacecraft potential in combination with magnetic field measurements by MAG to study fields and density fluctuations…

Multi-instrument analysis of far-ultraviolet aurora in the southern hemisphere of comet 67P/Churyumov-Gerasimenko

P. Stephenson, M. Galand, P. D. Feldman +9

Aims. We aim to determine whether dissociative excitation of cometary neutrals by electron impact is the major source of far-ultraviolet (FUV) emissions at comet 67P/Churyumov-Gera…
