Titan's atmosphere and surface liquid: New calculation using Statistical Associating Fluid Theory
Kargel, Jeffrey S.; Tan, Sugata P.; Marion, Giles M.
The application of PC-SAFT equation of state (EOS) in analyzing the in situ measurement of atmospheric data by Huygens probe reveals new insights into Titan's atmosphere and surface liquids. The EOS offers the most reliable and accurate calculations in fluid phase equilibria at the cryogenic conditions encountered in Titan and other extra-terrestr…
In Situ Measurements of the Size and Density of Titan Aerosol Analogs
Hörst, S. M.; Tolbert, M. A.
The organic haze produced from complex CH4/N2 chemistry in the atmosphere of Titan plays an important role in processes that occur in the atmosphere and on its surface. The haze particles act as condensation nuclei and are therefore involved in Titan's methane hydrological cycle. They also may behave like sediment on Titan's …
Can laboratory tholins mimic the chemistry producing Titan's aerosols? A review in light of ACP experimental results
Poch, O.; Szopa, C.; Coll, P. +7 more
The first results obtained by the ACP experiment onboard Huygens probe revealed that the main products obtained after thermolysis of Titan's collected aerosols, were ammonia (NH3) and hydrogen cyanide (HCN). Titan's aerosols, and their laboratory analogues named tholins, have been the subject of experimental or theoretical studies durin…
Photochemical activity of Titan’s low-altitude condensed haze
Gudipati, Murthy S.; Allen, Mark; Jacovi, Ronen +2 more
Titan, the largest moon of Saturn and similar to Earth in many aspects, has unique orange-yellow colour that comes from its atmospheric haze, whose formation and dynamics are far from well understood. Present models assume that Titan’s tholin-like haze formation occurs high in atmosphere through gas-phase chemical reactions initiated by high-energ…
A model of variability in Titan's atmospheric structure
Flasar, F. M.; Waite, J. H.; Lorenz, R. +2 more
Titan's atmosphere has been extensively studied during the Cassini-Huygens Mission. The polar environment undergoes considerable seasonal variation and is distinct from the more quiescent equatorial environment experienced by the Huygens probe in 2005. The thermal structure of the upper atmosphere is affected by interaction of Titan's atmosphere w…
Self-assembly of tholins in environments simulating Titan liquidospheres: implications for formation of primitive coacervates on Titan
Kawai, Jun; Jagota, Seema; Kaneko, Takeo +6 more
Titan, the largest satellite of Saturn, has a thick atmosphere containing nitrogen and methane. A variety of organic compounds have been detected in the atmosphere, most likely produced when atmospheric gases are exposed to ultraviolet light, electrons captured by the magnetosphere of Saturn and cosmic rays. The Cassini/Huygens probe showed that t…
The solubility of 40Ar and 84Kr in liquid hydrocarbons: Implications for Titan's geological evolution
Sotin, Christophe; Choukroun, Mathieu; Hodyss, Robert +1 more
solubility of argon and krypton in methane and ethane has been experimentally determined at Titan-relevant temperatures. At typical Titan surface temperature (94 K), argon and krypton solubilities are very large (47% in methane and 15% in ethane for Ar, 29% in methane and 43% in ethane for Kr), making liquid alkanes on Titan an important potential…
