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.

Magnetic Reconnection Driven by the Impact of a Magnetosheath High‐Speed Jet

Geophysical Research Letters
High‐speed jets (HSJs) are transient structures in the magnetosheath characterized by enhanced dynamic pressure. While recent studies report that HSJs trigger magnetic reconnection at the magnetopause, whether they can directly drive reconnection within ...

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 ...

Turbulent dynamo in the terrestrial magnetosheath. [PDF]

Nat Commun
Abstract Dynamo action refers to energy exchange processes through which magnetic fields are generated or/and amplified at the expense of kinetic energy of the plasma flows in various laboratory, space and astrophysical environments. The generation of the magnetic fields can take place over multiple spatial scales simultaneously.

Magnetosheath plasma flow model around Mercury [PDF]

Annales Geophysicae, 2021
The magnetosheath is defined as the plasma region between the bow shock, where the super-magnetosonic solar wind plasma is decelerated and heated, and the outer boundary of the intrinsic planetary magnetic field, the so-called magnetopause.

Plasma and Magnetic Field Turbulence in the Earth’s Magnetosheath at Ion Scales

Frontiers in Astronomy and Space Sciences, 2021
Crossing the Earth’s bow shock is known to crucially affect solar wind plasma including changes in turbulent cascade. The present review summarizes results of more than 15 years of experimental exploration into magnetosheath turbulence.

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.

South-north asymmetry of proton density distribution in the Martian magnetosheath

Earth and Planetary Physics, 2020
We perform a statistical analysis of data from the Mars Atmosphere and Volatile Evolution (MAVEN) project on the global distribution of protons in the Martian magnetosheath.
