The Effect of Fast Solar Wind on Ion Distribution Downstream of Earth’s Bow Shock

The Astrophysical Journal Letters
The solar wind gets thermalized and compressed when crossing a planetary bow shock, forming the magnetosheath. The angle between the upstream magnetic field and the shock normal vector separates the quasi-parallel from the quasi-perpendicular ...

Statistical Properties of the Distribution and Generation of Kinetic‐Scale Flux Ropes in the Terrestrial Dayside Magnetosheath

Geophysical Research Letters, 2023
The generation of kinetic‐scale flux ropes (KSFRs) is closely related to magnetic reconnection. Both flux ropes and reconnection sites are detected in the magnetosheath and can impact the dynamics upstream of the magnetopause.

Galileo PLS Plasma Observations During the E12 Europa Flyby Refuting an Encounter With a Cryovolcanic Plume

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract During Galileo's closest (“E12”) flyby of Europa, a brief burst of wave activity was recorded by the plasma wave instrumentation, PWS. This was speculatively interpreted by Jia et al. (2018, https://doi.org/10.1038/s41550‐018‐0450‐z) as a 2,100 cm−3 spike in plasma densities from a water plume encounter. While the plasma instrument, PLS, could

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

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract 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.

Searching for Electron‐Only Magnetic Reconnection on Lunar Crustal Magnetic Fields: A Case Study of Kaguya Low‐Altitude Observations

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Due to the lack of low‐altitude (<∼ ${< } \sim $50 km), high‐time‐resolution measurements, expected electron‐only magnetic reconnection near lunar magnetic anomalies (LMAs) has not been directly observed by lunar orbiters even though it is expected from numerical simulations and laboratory experiments.

Evaluation of Particle Scattering by Locally Generated Fast Magnetosonic Waves in the Martian Ionosphere

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Locally generated fast magnetosonic (local MS) waves in the Martian ionosphere have been reported recently, which are different from the solar wind‐driven MS waves. However, their effects on particle scattering have not been reported yet. This study pioneers the investigation of electron, proton, and oxygen atomic ion scattering induced by ...

Ion anisotropies in the magnetosheath

Geophysical Research Letters, 1993
One‐ and two‐dimensional initial value hybrid computer simulations are used with a magnetosheath parameter model to study the consequences of the growth of the mirror and ion cyclotron anisotropy instabilities. Magnetosheath observations have demonstrated inverse correlations between the proton and helium ion temperature anisotropies and the proton ...

Reconstructing the Geometry of a Hot Flow Anomaly With Bounding Jets in Magnetosheath

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract When interplanetary magnetic field discontinuities interact with planetary bow shocks, hot flow anomalies (HFAs) form in the solar wind and can extend into the magnetosheath. Here we reconstruct the three‐dimensional geometry of an HFA bounded by two jet regions in the terrestrial magnetosheath.

Experimental and numerical investigation of plasma parameters in the magnetosheath

MATEC Web of Conferences, 2018
We investigate the behaviour of the plasma parameters in the magnetosheath in a case when Interball-1 satellite stayed in the magnetosheath, crossing the tail magnetopause.

Geoeffectiveness of Magnetosheath Jets

, 2019
In this report we present spacecraft and ground-based observations of magnetosheath jets impacting the magnetosphere, both as a case study and a statistical study. In the case study, jets were detected in the magnetosheath by the Magnetospheric MultiScale mission, MMS.
