The evolution of Titan’s high-altitude aerosols under ultraviolet irradiation
Résumé
The Cassini-Huygens space mission discovered that Titan's thick brownish haze is initiated high in the atmosphere at an altitude of about 1000km. So far, nothing is known on the possible photochemical evolution of the organic aerosols composing the haze. Here, we address this aging process, simulating in the laboratory how solar vacuum ultraviolet irradiation affects the aerosols. The chemical evolution is monitored by infrared spectroscopy.
