The environment of a comet is a fascinating and unique laboratory to study plasma
processes and the formation of structures such as shocks and discontinuities from electron …

A major point of interest in cometary plasma physics has been the diamagnetic cavity, an
unmagnetized region in the innermost part of the coma. Here we combine Langmuir and …

Context. The Mutual Impedance Probe (MIP) of the Rosetta Plasma Consortium (RPC)
onboard the Rosetta orbiter which was in operation for more than two years, between …

The flow direction of low-energy ions around comet 67P/Churyumov–Gerasimenko has
previously been difficult to constrain due to the influence of the spacecraft potential. The Ion …

Comets are constantly interacting with the solar wind. When the comet activity is high
enough, this leads to the creation of a magnetic field free region around the nucleus known …

Analyzing data from the Ion Composition Analyzer on board the Rosetta spacecraft, we
studied a flow pattern of accelerated cometary ions (40–80 eV) inside and outside the …

We present a statistical survey of large amplitude, asymmetric plasma, and magnetic field
enhancements at comet 67P/Churyumov-Gerasimenko from December 2014 to June 2016 …

Abstract The European Space Agency/Rosetta mission to comet 67P/Churyumov‐
Gerasimenko has provided several hundred observations of the cometary diamagnetic …

We show that an ion‐ion cross‐field streaming instability between cold newborn cometary
ions and heated heavy ions that were picked up upstream is likely a contributing source of …

Context. Amongst the different features and boundaries encountered around comets, one
remains of particular interest to the plasma community: the diamagnetic cavity. Crossed for …
