Solar Wind Charge Exchange and Earth's Magnetosheath

The solar wind experiences a shock as it approaches Earth's magnetosphere. The region between this shock and the magnetosphere is called the magnetosheath. In this region the solar wind slows down and the solar wind density and temperature increase. This is particularly the case in the sub solar nose of the magnetosheath. This region can clearly be seen in the soft X-ray emission due to charge exchange between heavy solar wind ions and geocoronal neutral hydrogen. The inner and outer boundaries of the magnetosheath are called the magnetopause and the bow shock. These boundaries can easily be seen in the modeled results of solar wind charge exchange (SWCX). The objective of this paper is to show that we can detect these boundaries in the model by using a simulated moving spacecraft (from a range of locations) during a varying solar wind. For this purpose we have created a spacecraft trajectory about 30 RE from Earth and we have used the solar wind data of numerous magneto-hydrodynamic runs.
