AB - The shocked solar wind flows around the Earth’s magnetosphere in the magnetosheath downstreamof the Earth’s bow shock. Within this region, faster flows of plasma, called magnetosheath jets, arefrequently observed. These jets have been shown to sometimes exhibit supermagnetosonic speedsrelative to the magnetosheath flow and to develop bow waves or shocks of their own. Such jet-drivenbow waves have been observed to accelerate ions and electrons. We model electron acceleration bymagnetosheath jet-driven bow waves using test-particle Monte Carlo simulations. Our simulationssuggest that the energy increase of electrons with energies of a few hundred eV to 10 keV can beexplained by a collapsing magnetic trap forming between the bow wave and the magnetopause withshock drift acceleration at the moving bow wave. Our simulations allow us to estimate the efficiencyof acceleration as a function of different jet and magnetosheath parameters. Electron acceleration byjet-driven bow waves can increase the total acceleration in the parent shock environment, most likelyalso at shocks other than the Earth’s bow shock.
