Magnetosheath jets at Mars

H Gunell, M Hamrin, S Nesbit-Östman, E Krämer… - Science …, 2023‏ - science.org
Plasma entities, known as magnetosheath jets, with higher dynamic pressure than the
surrounding plasma, are often seen at Earth. They generate waves and contribute to energy …

Solar wind protons forming partial ring distributions at comet 67P

A Möslinger, GS Wieser, H Nilsson… - Journal of …, 2023‏ - Wiley Online Library
We present partial ring distributions of solar wind protons observed by the Rosetta

Explaining the evolution of ion velocity distributions at a low activity comet

A Moeslinger, H Gunell, H Nilsson… - Journal of …, 2024‏ - Wiley Online Library
At a low activity comet the plasma is distributed in an asymmetric way. The hybrid simulation
code Amitis is used to look at the spatial evolution of ion velocity distribution functions …

Particle-in-cell modelling of comet 67P/Churyumov-Gerasimenko-Spatial structures of densities and electric fields

H Gunell, C Goetz - Astronomy & Astrophysics, 2023‏ - aanda.org
Context. Sufficiently far from the Sun, all comets go through a phase of low activity. Rosetta
observations at large heliocentric distances of approximately 3 au showed that the plasma at …

Indirect observations of electric fields at comet 67P

A Moeslinger, H Nilsson… - Journal of …, 2023‏ - Wiley Online Library
No spacecraft visiting a comet has been equipped with instruments to directly measure the
static electric field. However, the electric field can occasionally be estimated indirectly by …
