The detection of solid phosphorus and fluorine in the dust from the coma of comet 67P/Churyumov-Gerasimenko
Esko Gardner, Harry J. Lehto, Kirsi Lehto +7
Here, we report the detection of phosphorus and fluorine in solid particles collected from the inner coma of comet 67P/Churyumov-Gerasimenko measured with the COmetary Secondary Io…
High-temperature measurements of VUV-absorption cross sections of CO2 and their application to exoplanets
Olivia Venot, Nicolas Fray, Yves Bénilan +6
UV absorption cross sections are an essential ingredient of photochemical atmosphere models. Exoplanet searches have unveiled a large population of short-period objects with hot at…
Inferring the interplanetary dust properties from remote observations and simulations
Jeremie Lasue, Anny-Chantal Levasseur-Regourd, Nicolas Fray +1
Since in situ studies and interplanetary dust collections only provide a spatially limited amount of information about the interplanetary dust properties, it is of major importance…
VUV-absorption cross section of carbon dioxide from 150 to 800 K and applications to warm exoplanetary atmospheres
Olivia Venot, Yves Bénilan, Nicolas Fray +9
Most exoplanets detected so far have atmospheric T significantly higher than 300K. Often close to their star, they receive an intense UV photons flux that triggers important photod…
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…
Laboratory Experiments to Understand Comets
Olivier Poch, Antoine Pommerol, Nicolas Fray +1
In order to understand the origin and evolution of comets, one must decipher the processes that formed and processed cometary ice and dust. Cometary materials have diverse physical…
