The Composition and Chemistry of Titan's Atmosphere

CA Nixon - ACS Earth and Space Chemistry, 2024 - ACS Publications
In this review I summarize the current state of knowledge about the composition of Titan's
atmosphere and our current understanding of the suggested chemistry that leads to that …

Detection of propadiene on Titan

NA Lombardo, CA Nixon, TK Greathouse… - The Astrophysical …, 2019 - iopscience.iop.org
The atmosphere of Titan, the largest moon of Saturn, is rich in organic molecules, and it has
been suggested that the moon may serve as an analog for the pre-biotic Earth due to its …

Absorption cross sections for ethane broadened by hydrogen and helium in the 3.3 micron region

R Dodangodage, PF Bernath, J Zhao… - Journal of Quantitative …, 2020 - Elsevier
The infrared absorption cross sections of ethane (C 2 H 6) have been measured in the 3.3

Hydrocarbon chemistry in the atmosphere of a Warmer Exo-Titan

D Adams, Y Luo, YL Yung - Frontiers in Astronomy and Space …, 2022 - frontiersin.org
Hosting a∼ 1.5 bar N2 atmosphere and reducing atmospheric composition, Titan has the
energy sources needed to drive disequilibrium chemistry and hosts an aerosol layer which …

Ethane clathrate hydrate infrared signatures for solar system remote sensing

E Dartois, F Langlet - Icarus, 2021 - Elsevier
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 …

New Constraints on Titan's Stratospheric n-Butane Abundance

BL Steffens, CA Nixon, K Sung, PGJ Irwin… - The Planetary …, 2022 - iopscience.iop.org
Curiously, n-butane has yet to be detected at Titan, though it is predicted to be present in a
wide range of abundances that span over 2.5 orders of magnitude. We have searched …
