Relativistic electron precipitation events driven by solar wind impact on the Earth's magnetosphere
Alexandra Roosnovo, Anton V. Artemyev, Xiao-Jia Zhang +6
Certain forms of solar wind transients contain significant enhancements of dynamic pressure and may effectively drive magnetosphere dynamics, including substorms and storms. An int…
Auroral, Ionospheric and Ground Magnetic Signatures of Magnetopause Surface Modes
M. O. Archer, M. D. Hartinger, L. Rastaetter +6
Surface waves on Earth's magnetopause have a controlling effect upon global magnetospheric dynamics. Since spacecraft provide sparse in situ observation points, remote sensing thes…
Magnetopause ripples going against the flow form azimuthally stationary surface waves
M. O. Archer, M. D. Hartinger, F. Plaschke +2
Surface waves process the turbulent disturbances which drive dynamics in many space, astrophysical and laboratory plasma systems, with the outer boundary of Earth's magnetosphere,…
Possible coexistence of kinetic Alfvén and ion Bernstein modes in sub-ion scale compressive turbulence in the solar wind
Owen Wyn Roberts, Daniel Verscharen, Yasuhito Narita +3
We investigate compressive turbulence at sub-ion scales with measurements from the Magnetospheric MultiScale Mission. The tetrahedral configuration and high time resolution density…
Statistical study of magnetosheath jet-driven bow waves
Terry Z. Liu, Heli Hietala, Vassilis Angelopoulos +3
When a magnetosheath jet (localized dynamic pressure enhancements) compresses ambient magnetosheath at a (relative) speed faster than the local magnetosonic speed, a bow wave or sh…
Electron acceleration and thermalization at magnetotail separatrices
C. Norgren, M. Hesse, P. Tenfjord +8
In this study we use the Magnetospheric Multiscale (MMS) mission to investigate the electron acceleration and thermalization occurring along the magnetic reconnection separatrices…
A Case for Electron-Astrophysics
Daniel Verscharen, Robert T. Wicks, Olga Alexandrova +27
A grand-challenge problem at the forefront of physics is to understand how energy is transported and transformed in plasmas. This fundamental research priority encapsulates the con…
On the deviation from Maxwellian of the ion velocity distribution functions in the turbulent magnetosheath
Silvia Perri, D. Perrone, E. Yordanova +20
The degree of deviation from the thermodynamic equilibrium in the ion velocity distribution functions (VDFs), measured by the Magnetospheric Multiscale (MMS) mission in the Earth's…
Direct observations of a surface eigenmode of the dayside magnetopause
M. O. Archer, H. Hietala, M. D. Hartinger +2
The abrupt boundary between a magnetosphere and the surrounding plasma, the magnetopause, has long been known to support surface waves. It was proposed that impulses acting on the…
How accurately can we measure the reconnection rate for the MMS diffusion region event of 2017-07-11?
Kevin J. Genestreti, Takuma Nakamura, Rumi Nakamura +8
We investigate the accuracy with which the reconnection electric field can be determined from in-situ plasma data. We study the magnetotail electron diffusion region observed…
Electron scale structures and magnetic reconnection signatures in the turbulent magnetosheath
E. Yordanova, Z. Vörös, A. Varsani +26
Collisionless space plasma turbulence can generate reconnecting thin current sheets as suggested by recent results of numerical magnetohydrodynamic simulations. The MMS mission pro…
Magnetospheric Multiscale Observations of Electron Vortex Magnetic Hole in the Magnetosheath Turbulent Plasma
S. Y. Huang, F. Sahraoui, Z. G. Yuan +29
We report the observations of an electron vortex magnetic hole corresponding to a new type of coherent structures in the magnetosheath turbulent plasma using the Magnetospheric Mul…
