Energy Deposition in Planetary Atmospheres by Charged Particles and Solar Photons

  title={Energy Deposition in Planetary Atmospheres by Charged Particles and Solar Photons},
  author={Jane L. Fox and M Galand and Robert E. Johnson},
We discuss here the energy deposition of solar FUV, EUV and X-ray photons, energetic auroral particles, and pickup ions. Photons and the photoelectrons that they produce may interact with thermospheric neutral species producing dissociation, ionization, excitation, and heating. The interaction of X-rays or keV electrons with atmospheric neutrals may produce core-ionized species, which may decay by the production of characteristic X-rays or Auger electrons. Energetic particles may precipitate… CONTINUE READING
