A sensitivity study of the Enceladus torus

We have developed a homogeneous model of physical chemistry to investigate the neutral‐dominated, water‐based Enceladus torus. Electrons are treated as the summation of two isotropic Maxwellian distributions: a thermal component and a hot component. The effects of electron impact, electron recombina...

Zusammenfassung:We have developed a homogeneous model of physical chemistry to investigate the neutral‐dominated, water‐based Enceladus torus. Electrons are treated as the summation of two isotropic Maxwellian distributions: a thermal component and a hot component. The effects of electron impact, electron recombination, charge exchange, and photochemistry are included. The mass source is neutral H2O, and a rigidly corotating magnetosphere introduces energy via pickup of freshly ionized neutrals. A small fraction of energy is also input by Coulomb collisions with a small population (
