WebOct 12, 2016 · Such shocks are generated when the solar wind slams into Earth’s magnetic field, undergoing a sudden slowdown. Bow shocks occur outside Earth’s magnetosphere, and therefore beyond the orbit of MMS. But a fluctuation in the solar wind can temporarily compress the magnetosphere, leaving the MMS spacecraft in the path of a bow shock. 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 … See more The defining criterion of a shock wave is that the bulk velocity of the plasma drops from "supersonic" to "subsonic", where the speed of sound cs is defined by $${\displaystyle c_{s}^{2}=\gamma p/\rho }$$ See more For several decades, the solar wind has been thought to form a bow shock at the edge of the heliosphere, where it collides with the surrounding interstellar medium. Moving away from … See more In 2006, a far infrared bow shock was detected near the AGB star R Hydrae. Bow shocks are also a common feature in Herbig Haro objects, … See more A similar effect, known as the magnetic draping effect, occurs when a super-Alfvenic plasma flow impacts an unmagnetized object such as what happens when the solar wind reaches the ionosphere of Venus: the flow deflects around the object … See more The best-studied example of a bow shock is that occurring where the Sun's wind encounters Earth's magnetopause, although bow shocks occur around all planets, both … See more Bow shocks form at comets as a result of the interaction between the solar wind and the cometary ionosphere. Far away from the Sun, a comet is an icy boulder without an atmosphere. As it approaches the Sun, the heat of the sunlight causes gas to be released from the … See more If a massive star is a runaway star, it can form an infrared bow-shock that is detectable in 24 μm and sometimes in 8μm of the Spitzer Space Telescope or the W3/W4-channels of See more
