Reformation of Supercritical Perpendicular Shock
Yuri V. Khotyaintsev, Domenico Trotta, Daniel B. Graham
Super-critical collisionless shocks are not static structures but evolve continuously as they reflect incoming ions back upstream. The physical process responsible for this non-sta…
Ion Temperature Anisotropy Limits from Magnetic Curvature Scattering in Magnetotail Reconnection Jets
Louis Richard, Anton V. Artemyev, Cecilia Norgren +3
In collisionless plasmas, relaxation of the deviations of ion velocity distribution functions (VDFs) from local thermodynamic equilibrium occurs through particle interactions with…
Electron Heat Flux and Whistler Instability in the Earth's Magnetosheath
Ida Svenningsson, Emiliya Yordanova, Yuri V. Khotyaintsev +4
Despite heat flux's role in regulating energy conversion in collisionless plasmas, its properties and evolution in the magnetosheath downstream of the Earth's bow shock are scarcel…
Non-Maxwellianity of Ion Velocity Distributions in the Earth's Magnetosheath
Louis Richard, Sergio Servidio, Ida Svenningsson +6
We analyze the deviations from local thermodynamic equilibrium (LTE) of the ion velocity distribution function (iVDF) in collisionless plasma turbulence. Using data from the Magnet…
Whistler waves in the quasi-parallel and quasi-perpendicular magnetosheath
Ida Svenningsson, Emiliya Yordanova, Yuri V. Khotyaintsev +3
In the Earth's magnetosheath (MSH), several processes contribute to energy dissipation and plasma heating, one of which is wave-particle interactions between whistler waves and ele…
AI in Space for Scientific Missions: Strategies for Minimizing Neural-Network Model Upload
Jonah Ekelund, Ricardo Vinuesa, Yuri Khotyaintsev +3
Artificial Intelligence (AI) has the potential to revolutionize space exploration by delegating several spacecraft decisions to an onboard AI instead of relying on ground control a…
The Persistent Mystery of Collisionless Shocks
Katherine Goodrich, Steven Schwartz, Lynn Wilson +14
Collisionless shock waves are one of the main forms of energy conversion in space plasmas. They can directly or indirectly drive other universal plasma processes such as magnetic r…
CMEs and SEPs During November-December 2020: A Challenge for Real-Time Space Weather Forecasting
Erika Palmerio, Christina O. Lee, M. Leila Mays +20
Predictions of coronal mass ejections (CMEs) and solar energetic particles (SEPs) are a central issue in space weather forecasting. In recent years, interest in space weather predi…
The solar-wind angular-momentum flux observed during Solar Orbiter's first orbit
Daniel Verscharen, David Stansby, Adam J. Finley +19
Aims: We present the first measurements of the solar-wind angular-momentum (AM) flux recorded by the Solar Orbiter spacecraft. Our aim is the validation of these measurements to su…
The structure of a perturbed magnetic reconnection electron diffusion region
G. Cozzani, Yu. V. Khotyaintsev, D. B. Graham +9
We report in situ observations of an electron diffusion region (EDR) and adjacent separatrix region. We observe significant magnetic field oscillations near the lower hybrid freque…
Shock Drift Acceleration of Ions in an Interplanetary Shock Observed by MMS
E. L. M. Hanson, O. V. Agapitov, I. Y. Vasko +6
An interplanetary (IP) shock wave was recorded crossing the Magnetospheric Multiscale (MMS) constellation on 2018 January 8. Plasma measurements upstream of the shock indicate effi…
Universality of lower hybrid waves at Earth's magnetopause
D. B. Graham, Yu. V. Khotyaintsev, C. Norgren +15
Waves around the lower hybrid frequency are frequently observed at Earth's magnetopause, and readily reach very large amplitudes. Determining the properties of lower hybrid waves i…
Electron Power-Law Spectra in Solar and Space Plasmas
M. Oka, J. Birn, M. Battaglia +10
Particles are accelerated to very high, non-thermal energies in solar and space plasma environments. While energy spectra of accelerated electrons often exhibit a power law, it rem…
Enhanced Magnetic Compressibility and Isotropic Scale-Invariance at Sub-Ion Larmor Scales in Solar Wind Turbulence
Khurom H. Kiyani, Sandra C. Chapman, Fouad Sahraoui +3
The anisotropic nature of solar wind magnetic turbulence fluctuations is investigated scale-by-scale using high cadence in-situ magnetic field measurements from the Cluster and ACE…
