WebCosmic Bow Shocks. Imagine an object moving at super-sonic speed. This object, as it moves through a medium, causes the material in the medium to pile up, compress, and heat up. The result is a type of shock wave, known as a bow shock. A bow shock gets it’s name from bow waves, the curved ridge of water in front of a fast-moving boat created ... WebCosmic Bow Shocks.

WebJun 11, 2024 · Solar wind plasma at the Earth's orbit carries transient magnetic field structures including discontinuities. Their interaction with the Earth's bow shock can significantly alter discontinuity configuration and stability. We investigate such an interaction for the most widespread type of solar wind discontinuities - rotational discontinuities … WebAug 6, 2009 · The cross-tail current that closes across the bow shock may be classified as the magnetic reconnection current, which we suggest is a new current system in the magnetosphere. In magnetospheric dynamics during southward IMF cases, we should take into account not only the regions inside the magnetopause but also the bow shock that …
WebAbstract. We present the first comprehensive statistical survey of the day-side terrestrial bow shock current system based on a large number of Cluster spacecraft bow shock crossings. Calculating the 3-D current densities using fluxgate magnetometer data and the curlometer technique enables the investigation of current locations, directions, and …
