Impact Ionization Double Peaks Analyzed In High Temporal Resolution On Solar Orbiter

Meyer-Vernet, Nicole; Mann, Ingrid; Vaverka, Jakub +6 more

Solar Orbiter is equipped with electrical antennas performing fast measurements of the surrounding electric field. The antennas register high-velocity dust impacts through the electrical signatures of impact ionization. Although the basic principle of the detection has been known for decades, the understanding of the underlying process is not comp…

Machine learning detection of dust impact signals observed by the Solar Orbiter

Mann, Ingrid; Vaverka, Jakub; Soucek, Jan +8 more

This article presents the results of automatic detection of dust impact signals observed by the Solar Orbiter - Radio and Plasma Waves instrument.

A sharp and characteristic electric field signal is observed by the Radio and Plasma Waves instrument when a dust particle impacts the spacecraft at high velocity. In this way, ∼ 5-20 dust impacts …

Dust observations with antenna measurements and its prospects for observations with Parker Solar Probe and Solar Orbiter

Issautier, Karine; Meyer-Vernet, Nicole; Mann, Ingrid +10 more

The electric and magnetic field instrument suite FIELDS on board the NASA Parker Solar Probe and the radio and plasma waves instrument RPW on the ESA Solar Orbiter mission that explore the inner heliosphere are sensitive to signals generated by dust impacts. Dust impacts have been observed using electric field antennas on spacecraft since the 1980…
