The role of the bow shock in solar wind-magnetosphere coupling

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… WebOn the bow shock in front of Earth’s magnetosphere flows a current due to the curl of the interplanetary magnetic field across the shock.
