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.

Large-Scale Solar Wind Phenomena Affecting the Turbulent Cascade Evolution behind the Quasi-Perpendicular Bow Shock

Universe, 2022
The Earth’s magnetosphere is permanently influenced by the solar wind. When supersonic and superalfvenic plasma flow interacts with the magnetosphere, the magnetosheath region is formed, which is filled with shocked turbulent plasma.

Magnetosheath jet evolution as a function of lifetime: global hybrid-Vlasov simulations compared to MMS observations [PDF]

Annales Geophysicae, 2021
Magnetosheath jets are regions of high dynamic pressure, which can traverse from the bow shock towards the magnetopause. Recent modelling efforts, limited to a single jet and a single set of upstream conditions, have provided the first estimations about ...

Magnetosheath jet properties and evolution as determined by a global hybrid-Vlasov simulation [PDF]

Annales Geophysicae, 2018
We use a global hybrid-Vlasov simulation for the magnetosphere, Vlasiator, to investigate magnetosheath high-speed jets. Unlike many other hybrid-kinetic simulations, Vlasiator includes an unscaled geomagnetic dipole, indicating that the simulation ...

Impact of Foreshock Transients on the Flank Magnetopause and Magnetosphere and the Ionosphere

Frontiers in Astronomy and Space Sciences, 2021
Mesoscale (on the scales of a few minutes and a few RE) magnetosheath and magnetopause perturbations driven by foreshock transients have been observed in the flank magnetotail.

Interball-1 observations of flux transfer events [PDF]

Annales Geophysicae, 2012
We present the results of a survey of 807 FTEs observed by Interball-1 on the mid- and high-latitude dayside and flank magnetopause. Dayside magnetosheath events show a strong tendency to occur for southward magnetosheath magnetic fields suggesting ...

On the origin of magnetosheath plasmoids and their relation to magnetosheath jets [PDF]

Journal of Geophysical Research: Space Physics, 2015
AbstractWe investigate localized magnetosheath and solar wind density enhancements, associated with clear magnetic field changes, and therefore referred to as magnetosheath/solar wind plasmoids, respectively. Using Cluster data, we show that there are two distinct populations of magnetosheath plasmoids, one associated with a decrease of magnetic field ...

Connection Between Foreshock Structures and the Generation of Magnetosheath Jets: Vlasiator Results

Geophysical Research Letters, 2021
Earth’s magnetosheath consists of shocked solar wind plasma that has been compressed and slowed down at the Earth’s bow shock. Magnetosheath jets are pulses of enhanced dynamic pressure in the magnetosheath. Jets have been observed by numerous spacecraft

Coherent wave activity in Mercury's magnetosheath [PDF]

Journal of Geophysical Research: Space Physics, 2015
AbstractThis study presents a statistical overview of coherent wave activity in Mercury's magnetosheath. Left‐handed electromagnetic ion cyclotron waves are commonly found behind the quasi‐perpendicular section of the bow shock, where they are present in ~50% of the spacecraft crossings of the magnetosheath.

Rotation of the magnetic field in Earth's magnetosheath by bulk magnetosheath plasma flow [PDF]

Annales Geophysicae, 2006
Abstract. Orientations of the observed magnetic field in Earth's dayside magnetosheath are compared with the predicted field line-draping pattern from the Kobel and Flückiger static magnetic field model. A rotation of the overall magnetosheath draping pattern with respect to the model prediction is observed. For an earthward Parker spiral, the sense of
