Profiles of dissociation and ionization rates in Triton’s atmosphere resulting from the seven reactions studied in this work. Solid lines represent individual reaction contributions and the dashed line the total rate. All profiles result from an incident H⁺ population with an energy of 50 keV, an incidence angle of 55°, and a scattering parameter of –0.5. Red horizontal lines mark the altitudes corresponding to the peak densities of electron (solid, 330 km) and N⁺ (dashed, 460 km) for reference.
