Magnetopause Boundary Layers

Journal of geomagnetism and geoelectricity, 1991
The formation of boundary layers inside and outside of the magnetopause discontinuity of the Earth is a consequence of mass and momentum transfer processes through the magnetopause. The existence of these boundary layers is well recognized nowadays. However, the physics related to for instance the transfer of energy through the magnetopause into the ...

Global MHD Simulations: Magnetosphere–Ionosphere Coupling Dependence on Conductance Model

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Eighty‐five geomagnetic storms were simulated with the space weather modeling framework Geospace model using two different ionospheric conductance models. One set used the legacy conductances within the Ridley ionosphere model, while the other set used the newly developed conductance model for extreme events conductance model.

Derivation of Ambient Electron Density Using Spacecraft Potential Measurements From the MMS and Van Allen Satellites: Application to the Plasmasphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract We investigate the empirical relationship between the spacecraft potential (Vs) measured by the Electric Field Double Probes, and the electron density (Ne) measured by the Fast Plasma Instrument on the MMS spacecraft. We derive their relationship during fast‐mode intervals when the Active Spacecraft Potential Control Devices are off.

Magnetic reconnection at the dayside magnetopause: Advances with MMS

, 2016
Magnetic reconnection is known to be an important process for coupling solar wind mass and momentum into the Earth's magnetosphere. Reconnection is initiated in an electron‐scale dissipation/diffusion region around an X line, but its consequences are ...

The effects of turbulence on three‐dimensional magnetic reconnection at the magnetopause [PDF]

, 2016
Two‐ and three‐dimensional particle‐in‐cell simulations of a recent encounter of the Magnetospheric Multiscale Mission (MMS) with an electron diffusion region at the magnetopause are presented.

Impact of Induced Electric Fields Inside the Magnetopause on Magnetopause Shadowing of Radiation Belt Electrons

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Loss of relativistic electrons with energies above 0.5 MeV through the magnetopause, commonly referred to as magnetopause shadowing, has been extensively investigated using both simulations and observations. However, direct and systematic observational evidence remains limited. In this study, we extend a previously developed magnetopause model

Magnetopause location modeling using machine learning: inaccuracy due to solar wind parameter propagation

Frontiers in Astronomy and Space Sciences
An intrinsic limitation of empirical models of the magnetopause location is a predefined magnetopause shape and assumed functional dependences on relevant parameters.

Investigation of the occurrence of significant deviations in the magnetopause location: solar-wind and foreshock effects [PDF]

Annales Geophysicae
Common magnetopause models can predict the location of the magnetopause with respect to upstream conditions from different sets of input parameters, including solar-wind pressure and the interplanetary magnetic field.

Different Transient Phenomena at the Edges of Traveling Foreshocks

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Past kinetic simulations and spacecraft observations have shown that traveling foreshocks (TFs) are bounded by either foreshock compressional boundaries (FCBs) or foreshock bubbles (FBs). Here we present four TFs with a different kind of structure appearing at one of their edges.

Transport of Mirror Mode Structures through Saturn’s Magnetopause Reconnection

The Astrophysical Journal
Magnetopause reconnection plays a significant role in transferring plasma and energy from the solar wind to planetary magnetospheres. Using a Cassini measurement, we reported a magnetopause reconnection at Saturn, identified by the Hall magnetic field ...
