WebMay 3, 2024 · In studies of physical processes near planetary bow shocks, empirical models of the latter are usually used. While computational magneto-hydrodynamics (MHD) or kinetic models of bow shocks are often more accurate, their computationally extensive nature limits their applicability to routine analysis of large volumes of data. 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. eagle zambia main news
