Evidence of a Subkinetic Spectral Break in a Strongly Turbulent Collisionless Plasma

The Astrophysical Journal
We investigate the magnetic ( B ) and electric ( E ) field spectra in the dissipation range of strong turbulence of a collisionless plasma. This investigation, which is relevant to turbulence studies in many astrophysical settings, is enabled by high ...

Substorm onset in the magnetotail.

Journal of geomagnetism and geoelectricity, 1978
Known signatures of the expansion phase onset in the magnetotail are summarized and discussed. A model is suggested for the nature of the multiple onset events. The importance is emphasized of observing the low-latitude magnetotail at |X|-10 to 15 RE at and shortly before the onset of the expansion phase.

Duskward displacement of plasmoids and reconnection in the near-Earth magnetotail

Earth, Planets and Space
Magnetic reconnection in the near-Earth magnetotail is responsible for explosive release of energy during substorms and auroral breakups. This near-tail reconnection was previously assumed to occur around the midnight meridian, where earthward flows were

Joint Observations of Energy Transport and Dissipation during Plasma Flow Vortex in the Terrestrial Magnetotail

The Astrophysical Journal
Plasma flow vorticity is ubiquitous in space and plays a key role in material mixing and energy transfer. The five THEMIS satellites orbiting in different regions of the terrestrial magnetotail provide an unprecedented opportunity to study the temporal ...

Cold Ion Energization by Secondary Magnetic Reconnection in a Turbulent Reconnection Jet During Storm Period

Geophysical Research Letters
During geomagnetic storms, cold ions from the ionosphere substantially contribute to the plasma sheet population, which may significantly impact magnetotail energy conversion and transport. However, the energization of cold ions in the magnetotail during

Magnetic Reconnection as a Potential Trigger for Magnetotail Flapping at Mars: Insights From MAVEN and Tianwen‐1 Observations

AGU Advances
Magnetotail current sheet (CS) flapping is a universal plasma phenomenon observed at multiple planets, yet its triggering mechanisms remain poorly understood outside of Earth.
