Plasma frequency waves in Earth's electron foreshock
Daniel B. Graham, Yuri V. Khotyaintsev, Mats André +2
At Earth's quasi-perpendicular bow shock, electrons can be reflected and accelerated to high velocities, forming beams. These beams excite Langmuir and beam-mode waves, which can t…
Occurrence of Flat-top Electron Velocity Distributions in Magnetotail Plasma Jets
Louis Richard, Yuri V. Khotyaintsev, Cecilia Norgren
Non-Maxwellian electron velocity distributions (eVDFs) are ubiquitous in collisionless plasmas. For example, various types of non-Maxwellian eVDFs exist in magnetic reconnection je…
Modelling spacecraft-emitted electrons measured by SWA-EAS experiment on board Solar Orbiter mission
Å . Å tverák, D. HerÄÃk, P. Hellinger +6
Thermal electron measurements in space plasmas typically suffer at low energies from spacecraft emissions of photo- and secondary electrons and from charging of the spacecraft body…
Ion-Scale Solitary Structures in the Solar Wind Observed by Solar Orbiter and Parker Solar Probe
Yufei Yang, Timothy S. Horbury, Domenico Trotta +12
We investigate a class of ion-scale magnetic solitary structures in the solar wind, characterized by distinct magnetic field enhancements and bipolar rotations over spatial scales…
Ion-Acoustic Waves and the Proton-Alpha Streaming Instability at Collisionless Shocks
Daniel B. Graham, Yuri V. Khotyaintsev, Ahmad Lalti
Ion-acoustic waves are routinely observed at collisionless shocks and could be an important source of resistivity. The source of instability and the effects of the waves are not fu…
