Estimating the fate of oxygen ion outflow from the high-altitude cusp
Slapak, Rikard; Schillings, Audrey; Haaland, Stein +2 more
We have investigated the oxygen escape-to-capture ratio from the high-altitude cusp regions for various geomagnetic activity levels by combining EDI and CODIF measurements from the Cluster spacecraft. Using a magnetic field model, we traced the observed oxygen ions to one of three regions: plasma sheet, solar wind beyond a distant X-line or daysid…
Magnetometer in-flight offset accuracy for the BepiColombo spacecraft
Plaschke, Ferdinand; Volwerk, Martin; Narita, Yasuhito +6 more
Recently the two-spacecraft mission BepiColombo launched to explore the plasma and magnetic field environment of Mercury. Both spacecraft, the Mercury Planetary Orbiter (MPO) and the Mercury Magnetospheric Orbiter (MMO, also referred to as Mio), are equipped with fluxgate magnetometers, which have proven to be well-suited to measure the magnetic f…
The fate of O+ ions observed in the plasma mantle: particle tracing modelling and cluster observations
Nilsson, Hans; Gunell, Herbert; Slapak, Rikard +5 more
Ion escape is of particular interest for studying the evolution of the atmosphere on geological timescales. Previously, using Cluster-CODIF data, we investigated the oxygen ion outflow from the plasma mantle for different solar wind conditions and geomagnetic activity. We found significant correlations between solar wind parameters, geomagnetic ac…
A deep insight into the ion foreshock with the help of test particle two-dimensional simulations
Lembège, Bertrand; Savoini, Philippe
Two-dimensional (2D) test particle simulations based on shock profiles issued from 2D full particle-in-cell (PIC) simulations are used in order to analyze the formation processes of ions back streaming within the upstream region after interacting with a quasi-perpendicular curved shock front. Two different types of simulations have been performed …
