Mhd Turbulence in Saturn's Magnetosheath Downstream of a Quasi Parallel Bow Shock

Mhd Turbulence in the Saturn`s Magnetosheath Downstream of a Quasi Perpendicular and a Quasi Parallel Shock

The magnetosphere of the Earth and the other planets contain a variety of low frequency (f < fp, fp being the proton gyrofrequency) waves. Several sources are known to contribute to these uctuations: (1) Waves present in the solar wind (mainly those occurring in the foreshock) are convected in the magnetosheath and possibly ampli ed passing through the shock front. (2) The bow shock modi es the...

High Energy Jets in the Earth’s Magnetosheath: Implications for Plasma Dynamics and Anomalous Transport

593 The region downstream of a supercritical collisionless shock, the magnetosheath (MSH), is known to be in a highly disturbed turbulent state [1–3]. The undisturbed solar wind (SW) streams with supermagnetosonic velocity V > c ms at a magnetosonic Mach number up to M ms ~ 15. At the Earth’s bow shock (BS), the SW decelerates to Mach numbers M ms < 1, thermalizes, and, when entering the MSH, i...

MMS Observation of Magnetic Reconnection in the Turbulent Magnetosheath

In this paper we use the full armament of the MMS (Magnetospheric Multiscale) spacecraft to study magnetic reconnection in the turbulent magnetosheath downstream of a quasi-parallel bow shock. Contrarily to the magnetopause and magnetotail cases, only a few observations of reconnection in the magnetosheath have been reported. The case study in this paper presents, for the first time, both fluid...

On the generation of magnetosheath high-speed jets by bow shock ripples

[1]The terrestrial magnetosheath is embedded with coherent high-speed jets of about 1RE in scale, predominantly during quasi-radial interplanetary magnetic field (IMF). When these high dynamic pressure (Pdyn) jets hit the magnetopause, they cause large indentations and further magnetospheric effects. The source of these jets has remained controversial. One of the proposed mechanisms is based on...
