Abstract Mercury’s magnetosphere is known to involve fundamental processes releasing particles and energy like at Earth due to the solar wind interaction. The resulting cycle is however much faster and involves acceleration, transport, loss, and re

Electron populations observed by Mercury Electron Analyzer onboard Mio/BepiColombo during its second Mercury flyby
Autor: Sae Aizawa, Nicolas Andre, Yoshifumi Saito, Moa Persson, Jean-Andre Sauvaud, Andrei Fedorov, Shoichiro Yokota, Alain Barthe, Emmanuel Penou, Mathias Rojo, Go Murakami
BepiColombo was launched in October 2018 and is currently en route to Mercury. Although its orbit insertion is planned for December 2025, BepiColombo will acquire new measurements during planetary flybys. During the cruise phase, the two spacecraft a

International audience; The Martian bow shock is a rich example of a supercritical, mass-loaded collisionless shock that coexists with ultra-low frequency upstream waves that are generated by the pick-up of exospheric ions. The small size of the bow

The Kelvin-Helmholtz instability (KHI) is a nonlinear shear-driven instability that develops at the interfaces between shear flows in plasmas. KHI is ubiquitous in plasmas and has been observed in situ at planetary interfaces and at the boundaries of
