Space Plasma Physics: A Review

Bruce T. Tsurutani, Gary P. Zank, Veerle J. Sterken +13

Owing to the ever-present solar wind, our vast solar system is full of plasmas. The turbulent solar wind, together with sporadic solar eruptions, introduces various space plasma pr…

Solar-wind electron precipitation on weakly magnetized bodies: the planet Mercury

Federico Lavorenti, Pierre Henri, Francesco Califano +4

Mercury is the archetype of a weakly magnetized, airless, telluric body immersed in the solar wind. Due to the lack of any substantial atmosphere, the solar wind directly precipita…

Opening the Black Box of the Radiation Belt Machine Learning Model

Donglai Ma, Jacob Bortnik, Xiangning Chu +3

Many Machine Learning (ML) systems, especially neural networks, are fundamentally regarded as black boxes since it is difficult to grasp how they function once they have been train…

Correlation between bandwidth and frequency of plasmaspheric hiss uncovered with unsupervised machine learning

Daniel Vech, David M. Malaspina, Alexander Drozdov +1

Previous statistical studies of plasmaspheric hiss investigated the averaged shape of the magnetic field power spectra at various points in the magnetosphere. However, this approac…

Tens to hundreds of keV electron precipitation driven by kinetic Alfvén waves during an electron injection

Y. Shen, A. V. Artemyev, X. -J. Zhang +9

Electron injections are critical processes associated with magnetospheric substorms, which deposit significant electron energy into the ionosphere. Although wave scattering of 1…

Electron dynamics in small magnetospheres: insights from global fully-kinetic plasma simulations of planet Mercury

Federico Lavorenti, Pierre Henri, Francesco Califano +4

The planet Mercury possesses a small but highly dynamic magnetosphere in which the role and dynamics of electrons are still largely unknown. We aim at modeling the global dynamics…

On the origin of "patchy" energy conversion in electron diffusion regions

Kevin J. Genestreti, Xiaocan Li, Yi-Hsin Liu +9

During magnetic reconnection, field lines interconnect in electron diffusion regions (EDRs). In some EDRs the reconnection and energy conversion rates are controlled by a steady ou…

Magnetic Flux Transport Identification of Active Reconnection: MMS Observations in Earth's Magnetosphere

Yi Qi, Tak Chu Li, Christopher T. Russell +3

Magnetic reconnection plays an important role in converting energy while modifying field topology. This process takes place in varied plasma environments in which the transport of…

Sub-Alfvenic Solar Wind observed by PSP: Characterization of Turbulence, Anisotropy, Intermittency, and Switchback

R. Bandyopadhyay, W. H. Matthaeus, D. J. McComas +18

In the lower solar coronal regions where the magnetic field is dominant, the Alfven speed is much higher than the wind speed. In contrast, the near-Earth solar wind is strongly sup…

MMS Observations of a Compressed Current Sheet: Importance of the Ambipolar Electric Field

Ami M. DuBois, Chris Crabtree, Gurudas Ganguli +2

Spacecraft data reveals a nonuniform ambipolar electric field transverse to the magnetic field in a thin magnetotail current sheet that leads to intense ExB velocity shear and non-…
