Earth bow shock
WebApr 1, 2002 · The Earth's bow shock is an integral part of the Sun–Earth connection, as it helps to slow and deflect the solar wind around the Earth's magnetosphere. Its location and shape is determined not only by the properties of the incident solar wind, but also in a self-consistent manner with the location and shape of the magnetosphere. WebJun 17, 2024 · Here we study and quantify ion acceleration at Earth's bow shock with observations from NASA's Magnetospheric Multiscale (MMS) satellites and in a global hybrid-Vlasov simulation. From the MMS observations, we find that quasiparallel shocks are more efficient at accelerating ions.
