The mirror mode: A "superconducting'' space plasma analogue

, 2018
We examine the physics of the magnetic mirror mode in its final state of saturation, the thermodynamic equilibrium, to demonstrate that the mirror mode is the analogue of a superconducting effect in a classical anisotropic-pressure space plasma.

Rapid Evolution of Super Equatorial Plasma Bubbles and X‐Pattern EIA Formation During Extreme Storm Conditions on 12 November 2025

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Extreme conditions during storms profoundly alter the evolution of equatorial plasma bubbles (EPBs), yet the key dynamics remains poorly understood. We document the rapid expansion, contraction, and decay of super EPBs in South America during the 12 November 2025 storm with Interplanetary Magnetic Field (IMF) Bz/By magnitude exceeding ∼50 nT ...

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 ...

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.

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 ...

Spatial distribution of plasma density and magnetic field amplitude in the dayside magnetosheath as a function of the IMF orientation

Frontiers in Astronomy and Space Sciences
The properties of the magnetosheath are of pivotal importance in determining the coupling between the magnetosphere and interplanetary medium. In particular, the magnetic flux pileup and plasma depletion layer (PDL) modify the boundary conditions of ...

Global MHD simulations of Saturns's magnetosphere at the time of Cassini approach [PDF]

, 2005
We present the results of a 3D global magnetohydrodynamic simulation of the magnetosphere of Saturn for the period of Cassini's initial approach and entry into the magnetosphere. We compare calculated bow shock and magnetopause locations with the Cassini

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.

Transport and entry of plasma clouds/jets across transverse magnetic discontinuities: Three-dimensional electromagnetic particle-in-cell simulations

, 2016
In this paper we use three-dimensional electromagnetic particle-in-cell simulations to investigate the interaction of a small-Larmor radius plasma cloud/jet with a transverse non-uniform magnetic field typical to a tangential discontinuity in a parallel ...

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.
