Ionization processes in the atmosphere of Titan. I. Ionization in the whole atmosphere

Gronoff, G.; Lilensten, J.; Desorgher, L. +1 more

Context: The Cassini probe regularly passes in the vicinity of Titan, revealing new insights into particle precipitation thanks to the electron and proton spectrometer. Moreover, the Huygens probe has revealed an ionized layer at 65~km induced by cosmic rays. The impact of these different particles on the chemistry of Titan is probably very strong…

Ionization processes in the atmosphere of Titan. II. Electron precipitation along magnetic field lines

Gronoff, G.; Lilensten, J.; Modolo, R.

Context: The Cassini probe regularly passes the vicinity of Titan, providing new insights into particle precipitation by use of its electron and ion spectrometers. A discrepancy between precipitation models and observations of electron fluxes has been found. This discrepancy was suspected to be caused by the geometry of the magnetic field.
