Electron Dynamics in Magnetosheath Mirror‐Mode Structures [PDF]

Journal of Geophysical Research: Space Physics, 2018
AbstractMirror‐mode structures are widely observed in space plasma environments. Although plasma features within the structures have been extensively investigated in theoretical models and numerical simulations, relatively few observational studies have been made, due to a lack of high‐cadence measurements of particle distributions in previous space ...

Mirror Mode Mediated EMIC Wave Generation in the Magnetosheath

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Electromagnetic ion cyclotron (EMIC) waves and mirror modes (MMs), both driven by ion temperature anisotropy, are commonly observed in planetary magnetosheaths. Conventional explanations for their co‐occurrence are largely based on linear instability theory in proton–electron plasmas, which requires comparable growth rates for the EMIC and MM ...

Fully Kinetic Simulations of Ion‐Acoustic Waves in Asymmetric Reconnection With Cold Ions

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract In collisionless plasma, ion‐acoustic wave (IAW) is an important candidate for enhancing resistivity and viscosity, yet their presence and role in magnetic reconnection remain poorly understood. Here, we employ 2.5‐D particle‐in‐cell simulations to investigate IAWs in asymmetric magnetopause reconnection involving a cold ion population ...

Three-dimensional Global Hybrid Simulation of Magnetosheath Jets at Mercury

The Astrophysical Journal Letters
Plasma high-speed jets are common in Earth’s magnetosheath, and they significantly perturb the magnetosheath and affect the magnetosphere. The space environment of Mercury, characterized by the bow shock, magnetosheath, and magnetosphere, shares many ...

THEMIS Observations of Particle Acceleration by a Magnetosheath Jet‐Driven Bow Wave

Geophysical Research Letters, 2019
Localized magnetosheath jets with high dynamic pressure are frequently observed downstream of Earth's bow shock. When such a fast magnetosheath jet compresses the ambient magnetosheath plasma, an earthward compressional bow wave could form.

Solar Activity Dependence of the Dayside Lunar Surface Potential in the Terrestrial Magnetotail

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract On the dayside of the Moon, the surface potential is primarily determined by (a) photoelectron emission by solar radiation and (b) the ambient plasma environment. Both of these drivers have large variability, but the resulting variability of the lunar surface potential has not been fully characterized yet.

An Investigation on the Apparent North‐South Asymmetry Identified in Multiple Current Sheet Crossing Events in Jovian Dawn Outer Magnetosphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Jovian magnetospheric dynamics are often believed to be mainly controlled by internal elements such as Jupiter's strong and fast‐rotating magnetic moment and Io's abundant volcanic escape, as these internal elements are powerful enough to control the magnetospheric dynamics, contrary to the internal elements of the earth's magnetosphere.

Ion velocity distributions within the LLBL and their possible implication to multiple reconnections [PDF]

Annales Geophysicae, 2004
We analyze two LLBL crossings made by the Interball-Tail satellite under a southward or variable magnetosheath magnetic field: one crossing on the flank of the magnetosphere, and another one closer to the subsolar point.

Ion Energization and Acceleration Associated With Foreshock Bubbles: Results From a Hybrid‐Vlasov Simulation and MMS Observations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Foreshock Bubbles (FBs) are large‐scale transient structures found in Earth's foreshock region and are associated with foreshock‐discontinuity interaction. FBs play a significant role in accelerating and energizing plasma through various mechanisms.

Mirror waves and mode transition observed in the magnetosheath by Double Star TC-1 [PDF]

Annales Geophysicae, 2009
The Double Star TC-1 magnetosheath pass on 26 February 2004 is used to investigate magnetic field fluctuations. Strong compressional signatures which last for more than an hour have been found near the magnetopause behind a quasi-perpendicular bow ...
