Description:
Magnetosheath jets are very common structures located downstream of Earth’s quasi-parallel bow shock characterized mainly by an increase in dynamic pressure. Although their properties and formation mechanisms have been investigated during the last 20 years nothing has been said about the influence and dynamics of alpha particles (He++), the second most important species in the solar wind after protons (H+ ), regarding jet evolution and characterization. In this work we perform a 2D local hybrid simulation (kinetic ions – fluid electrons) of a quasi- parallel (θ = 15 ), supercritical (M = 7) collisionless shock with 4% of He as a second specie in order to address these topics. Specifically, we analyze and compare the signatures of plasma parameters for both H+ and He++ as well as the associated Velocity Distribution Functions inside and around simulated jets.
