BepiColombo observations of cold oxygen and carbon ions in the flank of the induced magnetosphere of Venus

André, N.; Fedorov, A.; Krupp, N. +25 more

On 10 August 2021, the Mercury-bound BepiColombo spacecraft performed its second fly-by of Venus and provided a short-lived observation of its induced magnetosphere. Here we report results recorded by the Mass Spectrum Analyzer on board Mio, which reveal the presence of cold O⁺ and C⁺ with an average total flux of ~4 ± 1 × 10…

Whistler-mode waves in Mercury's magnetosphere observed by BepiColombo/Mio

Sahraoui, Fouad; Kasaba, Yasumasa; Omura, Yoshiharu +10 more

Whistler-mode chorus waves are natural electromagnetic emissions known to play a key role in electron acceleration and loss mechanisms via wave-particle interactions in planetary magnetospheres. Chorus waves have not yet been detected in Mercury's magnetosphere due to the lack of suitable instruments in the probes that previously visited the plane…
