Earth bow shock
WebJul 3, 2024 · Using in situ observations at Earth’s bow shock, we report that the interaction between electrons accelerated at quasi-parallel shocks and foreshock transients can explain the unexpected generation of relativistic electrons upstream of quasi-parallel bow shocks. RESULTS Simulations of a foreshock transient WebDec 14, 2024 · The first identification of ion-acoustic double layers and electron temperature variation across them in the Earth's bow shock Double layers have typical spatial width around 10 Debye lengths or one tenth of electron inertial length Typical potential drop across a double layer is 2%–7% of the cross-shock potential in the de Hoffmann-Teller frame

Scientist have termed this bow shock.
