Electron dynamics in small magnetospheres. Insights from global, fully kinetic plasma simulations of the planet Mercury

Henri, Pierre; André, Nicolas; Aizawa, Sae +4 more

Context. The planet Mercury possesses a small but highly dynamic magnetosphere in which the role and dynamics of electrons are still largely unknown.
Aims: We aim to model the global dynamics of solar-wind electrons impinging on Mercury's magnetosphere. Particular relevance is given to local acceleration processes and the global circulation p…

Tracking of magnetic helicity evolution in the inner heliosphere. A radial alignment study

Richter, I.; Narita, Y.; Hadid, L. Z. +5 more

Context. Magnetic helicity is one of the invariants in ideal magnetohydrodynamics, and its spectral evolution has a substantial amount of information to reveal the mechanism that are behind turbulence in space and astrophysical plasmas.
Aims: The goal of our study is to observationally characterize the magnetic helicity evolution in the inner…
