On the Kinetic Energy Input of Magnetosheath Jets Into the Magnetosheath
Geophysical Research LettersAbstract 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, to study the mass, momentum, and energy content of jets in the subsolar ...

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 ...

Magnetosheath jets at Mars [PDF]
Science Advances, 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 ...

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

First identification of mirror mode waves in Venus' magnetosheath?
Geophysical Research Letters, 2008 In this paper first time observations of mirror mode like structures in Venus' magnetosheath are presented. Using magnetometer data from the Venus Express spacecraft it is shown that in two regions in the Venusian magnetosheath strong compressional waves

Causes of Jets in the Quasi‐Perpendicular Magnetosheath [PDF]
Geophysical Research Letters, 2021 AbstractMagnetosheath jets are currently an important topic in the field of magnetosheath physics. It is thought that 97% of the jets are produced by the shock rippling at quasi‐parallel shocks. Recently, large statistical studies of magnetosheath jets have been performed, however, it is not clear whether rippling also produces jets found downstream of

Frontiers in Astronomy and Space SciencesA density structure within the magnetic cloud of an interplanetary coronal mass ejection impacted Earth and caused significant perturbations in plasma boundaries. Using spacecraft data, we describe the effects of this structure on the magnetosheath plasma downstream of the bow shock.

Honeycomb‐Like Magnetosheath Structure Formed by Jets: Three‐Dimensional Global Hybrid Simulations
Geophysical Research LettersMagnetosheath jets with enhanced dynamic pressure are common in the Earth's magnetosheath. They can impact the magnetopause, causing deformation of the magnetopause. Here we investigate the 3‐D structure of magnetosheath jets using a realistic‐scale, 3‐D

On the Magnetic Field Configuration of the Magnetosheath
Terrestrial, Atmospheric and Oceanic Sciences, 2013 The magnetosheath is the region where the shocked solar wind interacts directly with the magnetosphere. Here we examine the magnetic field throughout the equatorial magnetosheath as a function of the solar wind IMF direction using observational data sets (Geotail and Wind) spanning 9.5 years.

Correlation length of magnetosheath fluctuations: Cluster statistics [PDF]
Annales Geophysicae, 2008 Magnetosheath parameters are usually described by gasdynamic or magnetohydrodynamic (MHD) models but these models cannot account for one of the most important sources of magnetosheath fluctuations – the foreshock.
