Global Effects of Chorus and Hiss Waves on Trapped Energetic Electrons at Jupiter

Abstract Unlike Earth, where whistler‐mode chorus is generally observed outside the plasmasphere and hiss is predominantly confined within it, Jupiter's magnetosphere frequently hosts both wave modes simultaneously. Using Juno observations, we present a global survey of whistler‐mode waves at Jupiter, demonstrating that both chorus and hiss are prevalent over 6 < M < 13, with chorus confined to lower latitudes and hiss extending to higher latitudes. Based on the observed wave and plasma characteristics, we apply physics‐based global diffusion modeling to assess the separate and combined effects of chorus and hiss waves on energetic electron dynamics. The simulations show that, near regions of peak wave activity, chorus waves lead to net electron losses below ∼1 MeV while producing acceleration at higher energies. Hiss waves primarily drive electron losses, but in combination with chorus waves, they can also enable electron acceleration above ∼1 MeV at specific pitch angles.
