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 …

Abstract The Rosetta Orbiter Spectrometer for Ion and Neutral Analysis (ROSINA) instrument
onboard the Rosetta spacecraft has measured molecular oxygen (O 2) in the coma of comet …

The Rosetta mission provided detailed observations of the growth of a cavity in the solar
wind around comet 67P/Churyumov–Gerasimenko. As the comet approached the Sun, the …

Spacecraft charging is problematic for low‐energy plasma measurements. The charged
particles are attracted to or repelled from the charged spacecraft, affecting both the energy …

When a weakly outgassing comet is sufficiently close to the Sun, the formation of an ionized
coma results in solar wind mass loading and magnetic field dra** around its nucleus …

Context. The cometary ionosphere is immersed in fast flowing solar wind. A polarisation
electric field may arise for comets much smaller than the gyroradius of pickup ions because …

Average flow patterns of ions around comet 67P detected by the RPC-ICA instrument
onboard Rosetta are presented both as a time series and as a spatial distribution of the …

We present partial ring distributions of solar wind protons observed by the Rosetta
spacecraft at comet 67P/Churyumov‐Gerasimenko. The formation of ring distributions is …

We present and compare measurements of the spacecraft potential (V s/c) of the Rosetta
spacecraft throughout its stay in the inner coma of comet 67P/Churyumov–Gerasimenko, by …

Context. The direction of the interplanetary magnetic field determines the nature of the
interaction between a Solar System object and the solar wind. For comets, it affects the …
