The 3.4μm absorption in Titan’s stratosphere: Contribution of ethane, propane, butane and complex hydrogenated organics

  title={The 3.4$\mu$m absorption in Titan’s stratosphere: Contribution of ethane, propane, butane and complex hydrogenated organics},
  author={T. Cours and D. Cordier and B. Seignovert and L. Maltagliati and L. Biennier},
Abstract The complex organic chemistry harbored by the atmosphere of Titan has been investigated in depth by Cassini observations. Among them, a series of solar occultations performed by the VIMS instrument throughout the 13 years of Cassini revealed a strong absorption centered at ∼ 3 . 4 μ m . Several molecules present in Titan’s atmosphere generate spectral features in that wavelength region, but their individual contributions are difficult to disentangle. In this work, we quantify the… Expand

Ethane clathrate hydrate infrared signatures for solar system remote sensing
Abstract Hydrocarbons such as methane and ethane are present in many solar system objects, including comets, moons and planets. The interaction of these hydrocarbons with water ice at lowExpand
Distribution and intensity of water ice signature in South Xanadu and Tui Regio
Titan’s surface was revealed by Cassini ’s instruments, showing the presence of liquid hydrocarbons in lakes, and features like dry riverbed. In order to study the sediment transport in Titan’sExpand
Absorption cross sections for ethane broadened by hydrogen and helium in the 3.3 micron region
Abstract The infrared absorption cross sections of ethane (C2H6) have been measured in the 3.3 µm region by high resolution Fourier transform spectroscopy. The ethane samples had temperatures of 203,Expand
Laser Radiation Absorption in the Atmosphere of Titan
General formulas for the extinction coefficient of laser radiation in an atmosphere are derived. They take into account nonlinear effects and significantly differ from the linear optics results.Expand


A photochemical model of Titan's atmosphere and ionosphere
Abstract The model for Titan by Krasnopolsky (2014, Icarus 236, 83-91) has been adjusted to Pluto's conditions during the New Horizons flyby. The model includes 419 reactions of 83 neutrals and 33Expand
In this paper, we analyze the strong unidentified emission near 3.28 μm in Titan's upper daytime atmosphere recently discovered by Dinelli et al. We have studied it by using the NASA Ames PAH IRExpand
Three-micron extinction of the Titan haze in the 250–700 km altitude range: Possible evidence of a particle-aging process
Context. The chemical nature of the Titan haze is poorly understood. The investigation carried out by the Cassini-Huygens suite of instruments is bringing new insights into this question. Aims. ThisExpand
Retrieval and tentative indentification of the 3 μm spectral feature in Titan's haze
Recently, an unidentified 3.3–3.4 μm feature found in the solar occultation spectra of the atmosphere of Titan observed by Cassini/VIMS was tentatively attributed to the C–H stretching mode ofExpand
The Voyager 1 flyby of Titan in 1980 gave a first glimpse of the chemical complexity of Titan's atmosphere, detecting many new molecules with the infrared interferometer spectrometer (IRIS). TheseExpand
Elusive anion growth in Titan’s atmosphere: Low temperature kinetics of the C3N− + HC3N reaction
Ion chemistry appears to be deeply involved in the formation of heavy molecules in the upper atmosphere of Titan. These large species form the seeds of the organic aerosols responsible for the opaqueExpand
The role of benzene photolysis in Titan haze formation
Abstract During the Cassini mission to the saturnian system, benzene (C 6 H 6 ) was observed throughout Titan’s atmosphere. Although present in trace amounts, benzene has been proposed to be anExpand
The mesosphere and lower thermosphere of Titan revealed by Cassini/UVIS stellar occultations
Abstract Stellar occultations observed by the Cassini/UVIS instrument provide unique data that probe the mesosphere and lower thermosphere of Titan at altitudes between 400 and 1400 km. This regionExpand
Simulation of Titan’s atmospheric photochemistry - Formation of non-volatile residue from polar nitrile ices
We studied the photochemistry of frozen ice of a polar Titan’s atmospheric molecule cyanodiacetylene (HC5N) to determine the possible contribution of this compound to the lower altitudeExpand
Photochemical activity of Titan's low-altitude condensed haze.
It is demonstrated that indeed tholin-like haze formation could occur on condensed aerosols throughout the atmospheric column of Titan, and C4N2 ices undergo condensed-phase photopolymerization (tholin formation) at wavelengths as long as 355 nm pertinent to solar radiation reaching a large portion of Titan's atmosphere.
