The Effect of Fast Solar Wind on Ion Distribution Downstream of Earth’s Bow Shock

The Astrophysical Journal Letters
The solar wind gets thermalized and compressed when crossing a planetary bow shock, forming the magnetosheath. The angle between the upstream magnetic field and the shock normal vector separates the quasi-parallel from the quasi-perpendicular ...

Geoeffectiveness of Magnetosheath Jets

, 2019
In this report we present spacecraft and ground-based observations of magnetosheath jets impacting the magnetosphere, both as a case study and a statistical study. In the case study, jets were detected in the magnetosheath by the Magnetospheric MultiScale mission, MMS.

Spatial distribution of plasma density and magnetic field amplitude in the dayside magnetosheath as a function of the IMF orientation

Frontiers in Astronomy and Space Sciences
The properties of the magnetosheath are of pivotal importance in determining the coupling between the magnetosphere and interplanetary medium. In particular, the magnetic flux pileup and plasma depletion layer (PDL) modify the boundary conditions of ...

Experimental and numerical investigation of plasma parameters in the magnetosheath

MATEC Web of Conferences, 2018
We investigate the behaviour of the plasma parameters in the magnetosheath in a case when Interball-1 satellite stayed in the magnetosheath, crossing the tail magnetopause.

Thick escaping magnetospheric ion layer in magnetopause reconnection with MMS observations

Geophysical Research Letters, 2016
The structure of asymmetric magnetopause reconnection is explored with multiple point and high‐time‐resolution ion velocity distribution observations from the Magnetospheric Multiscale mission.

Kinetic evidence of magnetic reconnection due to Kelvin‐Helmholtz waves

Geophysical Research Letters, 2016
The Kelvin‐Helmholtz (KH) instability at the Earth's magnetopause is predominantly excited during northward interplanetary magnetic field (IMF). Magnetic reconnection due to KH waves has been suggested as one of the mechanisms to transfer solar wind ...

A case study of the plasma in the magneto-sheath using the numerical magnetosheath-magnetosphere model and THEMIS measure-ments

MATEC Web of Conferences, 2018
This paper presents a case study of the plasma parameters in the magnetosheath, based on THEMIS measurements. As a theoretical tool we apply the self-consistent magnetosheath-magnetosphere model.

Density depletion in an anisotropic magnetosheath

Geophysical Research Letters, 1996
We use a two dimensional model of the magnetosheath, not including the bow shock, to examine the effects of pressure anisotropy on magnetosheath structure. The simulation plane includes the Earth‐Sun direction and that of the incoming interplanetary magnetic field. Thus the crucial physical effects of compression and draping are both included.

Magnetic Field and Plasma Asymmetries Between the Martian Quasi‐Perpendicular and Quasi‐Parallel Magnetosheaths

Geophysical Research Letters
The Martian magnetosheath acts as a conduit for mass and energy transfer between the upstream solar wind and its induced magnetosphere. However, our understanding of its global properties remains limited. Using 9 years of data from NASA's Mars Atmosphere

Observations of energetic particle escape at the magnetopause: Early results from the MMS Energetic Ion Spectrometer (EIS)

Geophysical Research Letters, 2016
Energetic (greater than tens of keV) magnetospheric particle escape into the magnetosheath occurs commonly, irrespective of conditions that engender reconnection and boundary‐normal magnetic fields.
