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

Relaxation of the turbulent magnetosheath
Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACTIn turbulence, non-linear terms drive energy transfer from large-scale eddies into small scales through the so-called energy cascade. Turbulence often relaxes toward states that minimize energy; typically these states are considered globally.

Frontiers in Astronomy and Space Sciences, 2023 Introduction: During recent years magnetosheath plasma structures called “jets” are identified in spacecraft data as localized regions in the magnetosheath where the dynamic pressure is enhanced compared to the background.

Solar wind reconstruction from magnetosheath data using an adjoint approach [PDF]
Annales Geophysicae, 2015 We present a new method to reconstruct solar wind conditions from spacecraft data taken during magnetosheath passages, which can be used to support, e.g., magnetospheric models.

Kinetic‐Scale Turbulence in the Venusian Magnetosheath [PDF]
Geophysical Research Letters, 2020 AbstractWhile not specifically designed as a planetary mission, NASA's Parker Solar Probe (PSP) mission uses a series of Venus gravity assists (VGAs) in order to reduce its perihelion distance. These orbital maneuvers provide the opportunity for direct measurements of the Venus plasma environment at high cadence.

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

A model of the magnetosheath magnetic field during magnetic clouds [PDF]
Annales Geophysicae, 2014 Magnetic clouds (MCs) are huge interplanetary structures which originate from the Sun and have a paramount importance in driving magnetospheric storms. Before reaching the magnetosphere, MCs interact with the Earth's bow shock.
