The Rosetta mission provides an unprecedented possibility to study the interaction of
comets with the solar wind. As the spacecraft accompanies comet 67P/Churyumov …

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 …

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 …

Rosetta has followed comet 67P from low activity at more than 3.6 au heliocentric distance to
high activity at perihelion (1.24 au) and then out again. We provide a general overview of the …

Context. The ESA/Rosetta mission made it possible to monitor the plasma environment of a
comet, from near aphelion to perihelion conditions. To understand the complex dynamics …

Using a 3D fully kinetic approach, we disentangle and explain the ion and electron
dynamics of the solar wind interaction with a weakly outgassing comet. We show that, to first …

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 draping around its nucleus …

Context. Solar wind charge-changing reactions are of paramount importance to the physico-
chemistry of the atmosphere of a comet. The ESA/Rosetta mission to comet 67P/Churyumov …

Abstract In 2015 August, comet 67P/Churyumov–Gerasimenko, the target comet of the ESA
Rosetta mission, reached its perihelion at∼ 1.24 au. Here, we estimate for a three-day …

Context. On 20 January 2015 the Rosetta spacecraft was at a heliocentric distance of 2.5
AU, accompanying comet 67P/Churyumov-Gerasimenko on its journey toward the Sun. The …
