Ionization rate profiles in Triton’s atmosphere induced by three energy sources: solar EUV radiation, magnetospheric electron precipitation, and magnetospheric ion precipitation. The black curve represents our simulation results for ion-driven ionization For comparison, ionization rates from previous studies are shown: solar EUV-driven (orange) and electron-driven (blue) ionization from Strobel et al. (1990a), and electron-driven ionization (green) from Benne et al. (2024).
