Coordinated polar spacecraft, geosynchronous spacecraft, and ground-based observations of magnetopause processes and their coupling to the ionosphere [PDF]

open access: yesAnnales Geophysicae, 2004
In this paper, we present in-situ observations of processes occurring at the magnetopause and vicinity, including surface waves, oscillatory magnetospheric field lines, and flux transfer events, and coordinated observations at geosynchronous orbit by ...

Spatial dependence of magnetopause energy transfer: Cluster measurements verifying global simulations [PDF]

open access: yesAnnales Geophysicae, 2011
We investigate the spatial variation of magnetopause energy conversion and transfer using Cluster spacecraft observations of two magnetopause crossing events as well as using a global magnetohydrodynamic (MHD) simulation GUMICS-4.

Four-spacecraft determination of magnetopause orientation, motion and thickness: comparison with results from single-spacecraft methods [PDF]

open access: yesAnnales Geophysicae, 2004
In this paper, we use Cluster data from one magnetopause event on 5 July 2001 to compare predictions from various methods for determination of the velocity, orientation, and thickness of the magnetopause current layer. We employ established as well as

Magnetic Field Gradient Across the Flank Magnetopause

open access: yesFrontiers in Astronomy and Space Sciences, 2021
Magnetic pressure inside the magnetopause is usually balanced with a sum of thermal plasma and magnetic pressures on the magnetosheath side. However, observations reveal that the magnetosheath magnetic field can be frequently larger than that in the ...

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

open access: yesAnnales 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

open access: yesUniverse, 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.

Rotational/compressional nature of the magnetopause: Application of the BV technique on a magnetopause case study [PDF]

open access: yesJournal of Geophysical Research: Space Physics, 2014
The magnetopause boundary implies two main kinds of variations: a density/temperature gradient and a magnetic field rotation. Other variations are associated with these two, concerning in particular the flow velocity, the electric field, and the plasma composition.

Statistical analysis of magnetopause crossings at lunar distances [PDF]

open access: yesAnnales 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.

Concerning the location of magnetopause merging as a function of the magnetopause current strength [PDF]

open access: yesJournal of Geophysical Research: Space Physics, 1998
We start from an assumption that merging occurs in regions of the magnetopause where current strengths are greater than some threshold value which corresponds to the total jump in the field across the magnetopause greater than 50 nT. Because time and cost constraints preclude running numerical simulations for a wide variety of interplanetary magnetic ...
