Web2.1 Earth’s Bow Shock. The paradigm of a planetary bow shock embedded into a super-magnetosonic stellar wind flow is the Earth’s bow shock wave. Its continuous observation has fertilised the understanding of collisionless shock physics like no other shock neither in space nor in the laboratory. In astrophysics, a bow shock occurs when the magnetosphere of an astrophysical object interacts with the nearby flowing ambient plasma such as the solar wind. For Earth and other magnetized planets, it is the boundary at which the speed of the stellar wind abruptly drops as a result of its approach to the magnetopause. For stars, this boundary is typically the edge of the astrosphere, where the stell…

WebJun 11, 2024 · Solar wind plasma at the Earth's orbit carries transient magnetic field structures including discontinuities.
