Web29 sep. 2024 · As a test of the action of MHD turbulence in the solar wind, the compression of the heliospheric magnetic structure at 1AU by 109 interplanetary shocks is examined. In the magnetic structure the orientations of solar-wind strong current sheets are statistically examined vs. time in the downstream plasmas after shock compression. If the current … WebThe heliospheric current sheet, or interplanetary current sheet, is a surface separating regions of the heliosphere where the interplanetary magnetic field points toward and away from the Sun. [1] A small electrical current with a current density of about 10 −10 A /m 2 flows within this surface, forming a current sheet confined to this surface.

WebThe high-density, low-speed streams associated with the heliospheric current sheet (HCS) plasma impinging upon the Earth's magnetosphere cause positive Dst values (storm initial phases if followed by main phases). In the absence of shocks, SIs are infrequent during this phase of the solar cycle. WebThe Heliospheric Current Sheet (HCS) and Heliospheric Plasma Sheet (HPS) are the largest structures in the heliosphere and carry important information of fast and slow solar wind interaction and magnetic field variations. The HPS is distinguished by relatively high Beta, slow speed plasma that surrounding the HCS. Here, we report studies of …
