High-temperature measurements of acetylene VUV absorption cross sections and application to warm exoplanet atmospheres

Benjamin Fleury, Mathilde Poveda, Yves Benilan +9

Most observed exoplanets have high equilibrium temperatures. Understanding the chemistry of their atmospheres and interpreting their observations requires the use of chemical kinet…

Experimental investigations of diacetylene ice photochemistry in Titan's atmospheric conditions

Benjamin Fleury, Murthy S. Gudipati, Isabelle Couturier-Tamburelli

A large fraction of the organic species produced photochemically in the atmosphere of Titan can condense to form ice particles in the stratosphere and in the troposphere. According…

Nitrogen isotopic fractionation during abiotic synthesis of organic solid particles

Maïa Kuga, Nathalie Carrasco, Bernard Marty +5

The formation of organic compounds is generally assumed to result from abiotic processes in the Solar System, with the exception of biogenic organics on Earth. Nitrogen-bearing org…
