Unveiling the 3D Structure of Magnetosheath Jets

Monthly Notices of the Royal Astronomical Society, 2023
Magnetosheath jets represent localized enhancements in dynamic pressure observed within the magnetosheath. These energetic entities, carrying excess energy and momentum, can impact the magnetopause and disrupt the magnetosphere. Therefore, they play a vital role in coupling the solar wind and terrestrial magnetosphere. However, our understanding of the

MMS Observations of Electron Vorticity in the Earth’s Magnetosheath

The Astrophysical Journal
The Earth’s magnetosheath serves as a natural laboratory to study the transition of highly turbulent fluctuations. The fundamental information about plasma turbulences can be examined observationally with the help of electron vorticity measurements. This

Mshpy23: a user-friendly, parameterized model of magnetosheath conditions

Earth and Planetary Physics
Lunar Environment heliospheric X-ray Imager (LEXI) and Solar wind−Magnetosphere−Ionosphere Link Explorer (SMILE) will observe magnetosheath and its boundary motion in soft X-rays for understanding magnetopause reconnection modes under various solar wind ...

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.

Coincident ENA and Narrowband Radio Emissions as Diagnostics of Inward Plasma Transport at Saturn

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Saturn's kilometric radiation (SKR) and Energetic Neutral Atom (ENA) emissions are important diagnostics of the planet's magnetospheric dynamics, intensifying during global plasma injections and displaying characteristic planetary periodicity. Related to the SKR emissions are myriametric narrowband radio emissions that typically appear in the ...

Kinetic generation of whistler waves in the turbulent magnetosheath

Geophysical Research Letters, 2022
<p>Whistler waves, right-hand polarized waves with frequencies below the electron cyclotron frequency, are common in many space plasma regions such as the Earth’s magnetosheath. They can be generated by electron temperature anisotropy, in which case the instability grows through cyclotron resonance. A common way to determine

Foreshock Ion Properties at Earth's Bow Shock: Dependence on Upstream Conditions and Shock Geometry

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Solar wind ion reflection at collisionless shocks regulates foreshock plasma dynamics, yet the quantitative dependence of foreshock ion properties on upstream and shock‐related parameters remains unclear, causing difficulties in predicting foreshock disturbances.

Arase/LEPi Observations of Low‐Energy H+ and O+ Ion Fluxes in the Inner Magnetosphere: Implications for the Relationship Between Warm Plasma Cloak and Oxygen Torus

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract We investigated the spatial distributions and pitch‐angle distributions of 30–300 eV H+ and O+ ion fluxes using data obtained by the low‐energy particle experiments‐ion mass analyzer (LEPi) onboard the Arase satellite. A statistical analysis over 3.7 years reveals that the H+ ion flux is enhanced at L > 4 from the premidnight sector through ...

Coherent wave activity in Mercury's magnetosheath [PDF]

Journal of Geophysical Research: Space Physics, 2015
AbstractThis study presents a statistical overview of coherent wave activity in Mercury's magnetosheath. Left‐handed electromagnetic ion cyclotron waves are commonly found behind the quasi‐perpendicular section of the bow shock, where they are present in ~50% of the spacecraft crossings of the magnetosheath.

Low Frequency Extensions of Cyclotron Maser Instability‐Generated Radio Emission: A Statistical View From Cassini at Saturn

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract The Cassini spacecraft spent 13 years orbiting Saturn, quasi‐continuously measuring Saturn's radio emissions. One of the key elements of the radio spectrum at Saturn is the Saturn Kilometric Radiation (SKR), and several studies have been written on events called Low Frequency Extensions (LFEs) which represent strong, continuous extensions of ...
