Magnetopause stand-off distance in dependence on the magnetosheath and solar wind parameters [PDF]

Annales Geophysicae, 1998
A model of the magnetosheath structure proposed in a recent paper from the authors is extended to estimate the magnetopause stand-off distance from solar wind data.

DART: A Dual Aperture Relativistic Electron Telescope for Smallsats

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract The precipitation of particles into the Earth's atmosphere is a primary loss mechanism of the radiation belt for which many unknowns remain. With the growing number of space mission concepts to solve them, less expensive alternatives such as CubeSats are being used.

Magnetopause energy and mass transfer: results from a global MHD simulation [PDF]

Annales Geophysicae, 2006
We use the global MHD model GUMICS-4 to investigate the energy and mass transfer through the magnetopause and towards the closed magnetic field as a response to the interplanetary magnetic field (IMF) clock angle θ=arctan (BY/BZ), IMF magnitude ...

Simultaneous Observations of Electron Phase Space Density Variations in the Geostationary Orbit by GK2A, GOES‐16, and GOES‐17

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract This study presents simultaneous measurements of electron phase space density (PSD) gradients in geostationary orbit using data from GK2A, GOES‐16, and GOES‐17. By leveraging a three‐satellite configuration, we provide statistical results of PSD gradient estimation in invariant coordinates.

A linear perturbation analysis of magnetopause motion in the Newton-Busemann limit [PDF]

Annales Geophysicae, 1995
The response of the magnetopause surface to time-varying solar wind dynamic pressure is examined. We argue that to a first approximation the magnetopause surface may be considered as analogous to an elastic membrane. Upon displacement from equilibrium

Extending the Wave Telescope Technique to Larger Numbers of Spacecraft Obtaining Robust Spatial Power Spectra

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract The wave telescope is an analysis technique for multi‐point spacecraft data that estimates power spectra in reciprocal position space (k $k$‐space). It has been used to reveal the spatial properties of waves and fluctuations in space plasmas. Originally designed as an analysis tool for 4 spacecraft constellations, new multi‐scale missions such

The azimuthal extent of three flux transfer events [PDF]

Annales Geophysicae, 2008
In early 2006, the Cluster spacecraft crossed the dayside magnetopause twice each orbit with the spacecraft at their largest separation of the entire mission (~10 000 km).

Frequency Extensions of Auroral Kilometric Radiation: The Key to Unlocking Earth's Radio Response to Substorms

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Auroral kilometric radiation (AKR) provides a sensitive probe of magnetospheric dynamics during substorms. We analyze an extended data set of AKR bursts observed by the WIND spacecraft to investigate how the frequency structure of AKR responds to substorm onset and evolution.

Multi-spacecraft observations of broadband waves near the lower hybrid frequency at the Earthward edge of the magnetopause [PDF]

Annales Geophysicae, 2001
Broadband waves around the lower hybrid frequency (around 10 Hz) near the magnetopause are studied, using the four Cluster satellites. These waves are common at the Earthward edge of the boundary layer, consistent with earlier observations, and can

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 ...
