On the Kinetic Energy Input of Magnetosheath Jets Into the Magnetosheath

Geophysical Research Letters
Magnetosheath jets, plasma structures with enhanced dynamic pressure, are frequently observed in the terrestrial magnetosheath. However, their mass, momentum, and energy content are still unknown. We utilize Amitis, a 3D hybrid‐kinetic plasma simulation,

Characteristics of > 290 keV magnetosheath ions [PDF]

Annales Geophysicae, 1999
We performed a statistical analysis of 290-500 keV ion data obtained by IMP-8 during the years 1982-1988 within the earth's magnetosheath and analysed in detail some time periods withdistinct ion bursts.

Sunward flows in the magnetosheath associated with the magnetic pressure gradient and magnetosheath expansion

Frontiers in Astronomy and Space Sciences
A density structure within the magnetic cloud of an interplanetary coronal mass ejection impacted Earth and caused significant perturbations in plasma boundaries.

Magnetosheath jets at Mars. [PDF]

Sci Adv, 2023
Plasma entities, known as magnetosheath jets, with higher dynamic pressure than the surrounding plasma, are often seen at Earth. They generate waves and contribute to energy transfer in the magnetosheath. Affecting the magnetopause, they cause surface waves and transfer energy into the magnetosphere, causing throat auroras and magnetic signatures ...

Magnetosheath-cusp interface [PDF]

Annales Geophysicae, 2004
Abstract. We advance the achievements of Interball-1 and other contemporary missions in exploration of the magnetosheath-cusp interface. Extensive discussion of published results is accompanied by presentation of new data from a case study and a comparison of those data within the broader context of three-year magnetopause (MP) crossings by Interball-1.

Scale Sizes of Magnetosheath Jets [PDF]

Journal of Geophysical Research: Space Physics, 2020
AbstractMagnetosheath jets are plasma entities that feature a significantly enhanced dynamic pressure with respect to the ambient plasma. They occur more often downstream of the quasi‐parallel bow shock. Jets can propagate through the entire magnetosheath and impact on the magnetopause. We reanalyze multi‐spacecraft data from the Time History of Events

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 ...

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.

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 ...

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 ...
