The Cluster spacecrafts' view of the motion of the high-latitude magnetopause [PDF]

Annales Geophysicae
The magnetopause is the boundary between the interplanetary magnetic field and the terrestrial magnetic field. It is influenced by different solar-wind conditions, which lead to a change in the shape and location of the magnetopause.

Statistical analysis of magnetopause crossings at lunar distances [PDF]

Annales Geophysicae, 2019
Different magnetopause models with a diverse level of complexity are in use. One thing that they have in common is that they are mainly based on near-earth observations; i.e.

The local dayside reconnection rate for oblique interplanetary magnetic fields [PDF]

, 2016
We present an analysis of local properties of magnetic reconnection at the dayside magnetopause for various interplanetary magnetic field (IMF) orientations in global magnetospheric simulations.

Ion Dynamics at the Magnetopause of Ganymede [PDF]

Journal of Geophysical Research: Space Physics, 2022
AbstractWe study the dynamics of the thermal O+ and H+ ions at Ganymede's magnetopause when Ganymede is inside and outside of the Jovian plasma sheet using a three‐dimensional hybrid model of plasma (kinetic ions, fluid electrons). We present the global structure of the electric fields and power density (E ⋅ J) in the magnetosphere of Ganymede and show

Ion escape from the high latitude magnetopause: analysis of oxygen and proton dynamics in the presence of magnetic turbulence [PDF]

Annales Geophysicae, 2007
Recent Cluster observations of the vicinity of the high latitude magnetopause indicate the presence of beams of singly charged oxygen ions, which are of ionospheric origin.

Excess of Sodium Ions Density Required to Create a Wide Current at the Hermean Magnetopause

Universe, 2021
In this paper we consider an unusual structure, twice observed at the magnetopause of Mercury, and called the “Double Magnetopause”. Presumably, it is associated with a current sheet created by Na+ ions. Two alternative scenarios are considered.

Kelvin-Helmholtz Instability of the Magnetopause of Disc-Accreting Stars [PDF]

, 2009
This work investigates the short wavelength stability of the magnetopause between a rapidly-rotating, supersonic, dense accretion disc and a slowly-rotating low-density magnetosphere of a magnetized star.

Electrodynamic context of magnetopause dynamics observed by magnetospheric multiscale

Geophysical Research Letters, 2016
Magnetopause observations by Magnetospheric Multiscale (MMS) and Birkeland currents observed by the Active Magnetosphere and Planetary Electrodynamics Response Experiment are used to relate magnetopause encounters to ionospheric electrodynamics.

ULF waves in the low‐latitude boundary layer and their relationship to magnetospheric pulsations: A multisatellite observation [PDF]

, 1991
On April 30 (day 120), 1985, the magnetosphere was compressed at 0923 UT and the subsolar magnetopause remained near 7 REgeocentric for ∼2 hours, during which the four spacecraft Spacecraft Charging At High Altitude (SCATHA), GOES 5, GOES 6, and Active ...

The initial temporal evolution of a feedback dynamo for Mercury

, 2010
Various possibilities are currently under discussion to explain the observed weakness of the intrinsic magnetic field of planet Mercury. One of the possible dynamo scenarios is a dynamo with feedback from the magnetosphere. Due to its weak magnetic field
