Spectral Properties and Energy Injection in Mercury's Magnetotail Current Sheet

Geophysical Research Letters
Mercury's magnetotail hosts a thin and highly dynamic current sheet (CS), where magnetic reconnection and strong fluctuations frequently occur. Here, we statistically analyze magnetic field power spectra across 370 magnetotail CSs observed by MESSENGER ...

PIC Simulations of Overstretched Ion‐Scale Current Sheets in the Magnetotail

Geophysical Research Letters, 2023
Onset of reconnection in the tail requires the current sheet thickness to be of the order of the ion thermal gyroradius or smaller. However, existing isotropic plasma models cannot explain the formation of such thin sheets at distances where the X‐lines ...

Estimates of magnetotail reconnection rate based on IMAGE FUV and EISCAT measurements [PDF]

Annales Geophysicae, 2005
Dayside merging between the interplanetary and terrestrial magnetic fields couples the solar wind electric field to the Earth's magnetosphere, increases the magnetospheric convection and results in efficient transport of solar wind energy into the ...

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).

Data Mining Reconstruction of Magnetotail Reconnection and Implications for Its First-Principle Modeling

Frontiers in Physics, 2021
Magnetic reconnection is a fundamental process providing topological changes of the magnetic field, reconfiguration of space plasmas and release of energy in key space weather phenomena, solar flares, coronal mass ejections and magnetospheric substorms ...

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

Magnetotail Physics

Eos, Transactions American Geophysical Union, 1988
When a rapidly moving low‐density plasma encounters a massive magnetized object in space, a tail of magnetic field lines typically forms behind the object. Some of the field lines that thread through the central body are stretched out in the downstream direction be cause of frictional processes that act between the body's own field lines and the ...

Magnetic Reconnection in the Martian Magnetotail: Occurrence Rate and Impact on Ion Loss

Geophysical Research Letters, 2023
The current sheet is crucial in releasing magnetic free energy in cosmic plasmas via fast magnetic reconnection or wave excitation. This research investigates the characteristics of the Martian tail current sheet by analyzing data acquired from the Mars ...
