Optical indices of organic aerosols for oxidizing atmospheres of Earth-like exoplanets

Abstract : Photochemical haze is likely produced in most planetary atmospheres. Optical indices are required to evaluate the haze contribution to the climate of aplanet. Unfortunately few experimental data exist and most of them have been measured with laboratory analogs of Titan’s haze, which can only be amodel scenario fortotally reduced atmospheres. In the present work we studythe optical indices in the UV-Vis range ofanalogs of planetary organic haze produced with CO2/CH4ratios varying between 1 and 4 in order to provide appropriate optical indices for a large range of Earth-like oxidizingatmospheres. Oxidized analogues are found as much as four times better absorbers in the UVthan the reduced ones.
