Testing adiabatic models of energetic electron acceleration at dipolarization fronts

Frontiers in Astronomy and Space Sciences, 2023
Betatron acceleration is commonly cited as a primary accelerator of energetic electrons at dipolarization fronts, and many case studies compare observed energetic electrons measurements to a betatron model.

Mesoscale phenomena and their contribution to the global response: a focus on the magnetotail transition region and magnetosphere-ionosphere coupling

Frontiers in Astronomy and Space Sciences, 2023
An important question that is being increasingly studied across subdisciplines of Heliophysics is “how do mesoscale phenomena contribute to the global response of the system?” This review paper focuses on this question within two specific but interlinked

Juno Observations of Ion‐Inertial Scale Flux Ropes in the Jovian Magnetotail

Geophysical Research Letters, 2021
Two ion‐inertial scale magnetic flux ropes are identified in the Juno magnetic field measurements in the dawnside Jovian magnetotail. Previously reported plasmoids in this region had typical diameters of several Jovian radii (RJ).

Ion distribution functions in magnetotail reconnection: global hybrid-Vlasov simulation results [PDF]

Annales Geophysicae, 2021
We present results of noon–midnight meridional plane global hybrid-Vlasov simulations of the magnetotail ion dynamics under a steady southward interplanetary magnetic field using the Vlasiator model.

Electron‐Scale Measurements of Antidipolarization Front

Geophysical Research Letters, 2021
Antidipolarization fronts (ADFs), usually formed at the leading edge of the tailward reconnection jets in the Earth's magnetotail, are characterized by sharp enhancements of southward magnetic field (negative Bz). The fine structures at electron scale of

Contribution of magnetotail currents to Dst index during different intensity magnetic storms: a global MHD model study

Frontiers in Astronomy and Space Sciences
The Disturbance Storm Time (Dst) index serves as a critical indicator for quantifying geomagnetic storm intensity; however, the precise contribution of magnetotail currents to its formation remains inadequately characterized.

The Dynamic Response of Jovian Magnetotail Reconnection to Enhanced Solar Wind Ram Pressure

The Astrophysical Journal
In this study, we employ the Grid Agnostic Magnetohydrodynamic (MHD) for Extended Research Applications (GAMERA), a high-resolving-power, three-dimensional global MHD model, to simulate magnetotail reconnection in Jupiter's magnetosphere.

Rapid Response of Martian Magnetotail to Solar Wind Disturbance: Tianwen‐1 and MAVEN Joint Observations

Geophysical Research Letters
The Martian magnetotail is largely controlled by the solar wind (SW) and is modulated by variations in the upstream drivers. However, due to the limitations of single‐spacecraft observations, the effects of SW variations on the Martian magnetotail have ...
