A Coupled Model of Titan's Atmosphere and Ionosphere

Lara, L. M.; Rodrigo, R.; López-Moreno, J. J. +2 more

The paper deals with a coupled model of the upper atmosphere and ionosphere of Titan. The neutral atmosphere is described by a comprehensive photochemical model for 30° solar zenith angle with molecular and turbulent diffusive transport taken into account. At the upper boundary (1430 km) escaping flux of light molecules is included in boundary con…

Exobiological Implications of a Possible Ammonia-Water Ocean inside Titan

Fortes, A. D.

Models of Titan's thermal history indicate that an ocean consisting of an ammonia-water solution, as much as 200 km deep, is presently concealed beneath a crust of water ice. Conditions within this hypothetical ocean are discussed here and compared with conditions in terrestrial biomes. These conditions, while extreme by terrestrial standards, are…
