Scientists use the Earth as a tool for astrobiology by analyzing planetary field analogues (ie terrestrial samples and field sites that resemble planetary bodies in our Solar System). In …
The discovery of large (> 100 u) molecules in Titan's upper atmosphere has heightened astrobiological interest in this unique satellite. In particular, complex organic aerosols …
UV radiation can induce photochemical processes in exoplanet atmospheres and produce haze particles. Recent observations suggest that haze and/or cloud layers could be present …
Powdered samples of carbon–nitrogen-hydrogen “tholins” that mimic Titan's atmosphere aerosols were produced under levitation conditions in the laboratory with a dusty plasma …

We report new optical constants (refractive index, n, and extinction coefficient, k) for exoplanet haze analogs from 0.3 to 30 µm. The samples were produced in a simulated N 2 …
The surfaces of many objects in the Solar System comprise substantial quantities of water ice sometimes mixed with minerals and/or organic molecules. The sublimation of the ice …
Here we present the first quantitative study of the gas to solid particle conversion in a Radio Frequency dusty plasma experiment simulating the complex atmospheric reactivity on Titan …

In this work Titan's atmospheric chemistry is simulated using a capacitively coupled plasma radio frequency discharge in a N2− CH4 stationnary flux. Samples of Titan's tholins are …
This work presents the first study of the gaseous products resulting from the partial dissociation of methane and nitrogen in the PAMPRE experimental setup simulating Titan's …
