Will Nanodust Reappear in STEREO/WAVES Data?

Le résumé fourni par la source

Abstract Nanodust particles produced near the Sun by collisional breakup of larger grains are accelerated in the magnetised solar wind and reach high speeds outwards of 1 au. Vaporisation and ionization of fast dust grains impacting a spacecraft produce voltage pulses on wave instruments that enable them to act as dust detectors. Wave instruments on STEREO and on Cassini during its cruise phase detected a highly variable flux of fast nanodust. Both detections took place when the orientation of the solar magnetic dipole produced an interplanetary electric field that focused nanoparticles towards the heliospheric current sheet—a geometry that is recurring because of the periodicity of solar activity.
