Résumé

Thermospheres of exoplanets are submitted to the harsh UV and X-ray radiations of their host star. In the present work we focus on ion chemistry occurring in super-Earths and mini-Neptunes. We simulate in the laboratory the effect of Far-UV on gas-mixtures varying from H 2-rich to H 2-poor conditions and we analyze the ions by in situ mass spectrometry.
