Magnetic holes at the ion-to-electron kinetic scale (KSMHs) are one of the extremely small
intermittent structures generated in turbulent magnetized plasmas. In recent years, the …

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 spacecraft has escorted comet 67P/Churyumov‐Gerasimenko since 6 August
2014 and has offered an unprecedented opportunity to study plasma physics in the coma …

The coronal heating region is able to generate mirror mode structures by ion mirror
instabilities. Linear magnetic holes are believed to be the remnants of mirror mode …

The small-scale linear magnetic hole (LMH) is a magnetic dip with a size less than or on the
order of ρ i (proton gyroradius), which may contribute to turbulence properties in the solar …

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 …

Because ion–neutral reaction cross sections are energy dependent, the distance from a
cometary nucleus within which ions remain collisionally coupled to the neutrals is dictated …

The magnetic field at a comet is significantly influenced by the solar wind on one side and
the outgassing rate on the other. There are no simple spatial models for the magnetic field …

Despite the long escort by the ESA Rosetta mission, direct observations of a fully developed
bow shock around 67P/Churyumov–Gerasimenko have not been reported. Expanding on …
