Rotation‐Controlled Diurnal Evolution of Uranus' Asymmetric Bow Shock at Equinox

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract Uranus possesses the most extreme magnetic and rotational geometry in the solar system, resulting in a uniquely dynamic and asymmetric interaction between its magnetosphere and the solar wind. Here we investigate the diurnal evolution of the Uranian bow shock (BS) at equinox using global multifluid magnetohydrodynamic simulations constrained ...

Geoelectric Field Caused by Flux Transfer Events in an Ionosphere‐Coupled Vlasiator Simulation

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract We report on the relationship between flux transfer events (FTEs) at Earth's magnetopause and the geoelectric field that is induced near the FTEs' magnetic footpoints. We study this system using the global hybrid‐Vlasov code Vlasiator, which has recently been extended to model ionospheric physics.

Cluster PEACE observations of electron pressure tensor divergence in the magnetotail

, 2006
Cluster crossed the magnetotail neutral sheet on four occasions between 16: 38 and 16: 43 UT on 08/17/2003. The four-spacecraft capabilities of Cluster are used to determine spatial gradients from the magnetic field vectors and, for the first time, full ...

Long‐Term Trends in the Calibration of the Cluster Fluxgate Magnetometer Instruments

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract The calibration parameters of the Cluster mission's fluxgate magnetometer instruments have been determined and updated on a per‐orbit basis throughout the 24 years of the mission. Since there is no absolute field reference for vector measurements in‐flight, various spacecraft‐to‐spacecraft and instrument‐to‐instrument comparisons have been ...

Importance of the dusk-dawn interplanetary magnetic field component (IMF By) to magnetospheric convection in Earth’s magnetotail plasma sheet

Frontiers in Astronomy and Space Sciences
The solar wind and its embedded magnetic field, the interplanetary magnetic field (IMF) together with magnetic reconnection power the large-scale plasma and magnetic flux circulation in the Earth’s magnetosphere-ionosphere system.

Collisionless reconnection in Jupiter's magnetotail

Geophysical Research Letters, 1991
We present the first quantitative study of collisionless reconnection in Jupiter's magnetotail. Recently it has been shown that collisionless reconnection can occur in the Earth's magnetotail quasi‐neutral sheet when the electrons are subject to chaotic pitch angle diffusion.

Ion Anisotropy in Earth's Magnetotail: Importance of High‐Energy Ions

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract The reconfiguration of the magnetotail current sheet during substorms often includes the formation of a thin current sheet (TCS) with a strong magnetic field line tension force. This force cannot be balanced by isotropic plasma pressure gradients, and force balance in such a TCS requires ion anisotropy and/or agyrotropy of plasma pressure.

Magnetotail Source of Premidnight Upward Field‐Aligned Currents: Nature of the Substorm Current System

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract The substorm current wedge constitutes the backbone of the substorm current system. Its field‐aligned current components include an upward current in the premidnight sector and a downward current in the midnight‐morning sector, which connect the auroral ionosphere to the magnetotail.

On Spontaneous Reconnection in the Earth's Magnetotail

Journal of geomagnetism and geoelectricity, 1991
The release of energy stored in the Earth's magnetotail is a major feature of the coupling between solar wind and magnetosphere. Spontaneous reconnection due to tearing mode instability in the magnetotail provides an appropriate mechanism, explaining energy release, delays the response to changes in the interplanetary medium, non stationary features of

Reinvestigating the Nightside Ionosphere of Mars With 8 Years of Mars Express and MAVEN Data

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract Tailward ion escape in the nightside magnetotail is one of the dominant paths of ion escape from Mars. The Martian nightside ionosphere can serve as a major reservoir for this escape channel, but its global distributions and dependence on the upstream solar wind have not been fully investigated due to observational limitations.
