Dust observations with antenna measurements and its prospects for observations with Parker Solar Probe and Solar Orbiter
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-12-10)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 1980s and the method was recently used with a number of ... -
Machine Learning Detection of Dust Impact Signals Observed by The Solar Orbiter
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-11)This article present results from automatic detection of dust impact signals observed by the Solar Orbiter – Radio and Plasma Waves instrument.<p> <p>A sharp and characteristic electric field signal is observed by the Radio and Plasma Waves instrument when a dust particle impact the spacecraft at high velocity. In this way, ∼5–20 dust impacts are daily detected as the Solar Orbiter travels through ... -
Modeling Solar Orbiter dust detection rates in the inner heliosphere as a Poisson process
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-20)Context. Solar Orbiter provides dust detection capability in the inner heliosphere, but estimating physical properties of detected dust from the collected data is far from straightforward.<p> <p>Aims. First, a physical model for dust collection considering a Poisson process is formulated. Second, it is shown that dust on hyperbolic orbits is responsible for the majority of dust detections with ... -
Understanding Cassini RPWS Antenna Signals Triggered by Dust Impacts
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-09-04)Electric field antennas are capable of detecting dust impacts in different space environment. We analyze the dust impact signals detected by the Cassini Radio and Plasma Wave Science instrument at different locations around Saturn and compare them with dust impact signals simulated in laboratory conditions and numerically. The spacecraft potential, the size, and capacitance of the impacted element ... -
