Titan's aerosols : chemistry and optical behaviour
Abstract
This presentation deals with the most recent results about aerosol analogues of Titan's atmosphere being produced at LISA, and that are considered as the most representative laboratory analogues (Coll et al., PSS, 1999; McKay et al., PSS, in press). We will present here the latest data concerning the refractive complex index of this material (Ramirez et al., Icarus, accepted). These results are of crucial importance for various research fields such as radiative transfer and surface behaviour modeling. We will also discuss the results of a comparative chemical analysis of several products (Poly-C2H4, different Poly-HCN samples...), as well as Titan's aerosols analogues (obtained from different different energy sources). We will highlight the different families of such analogues (Coll et al., in preparation). Finally we will conclude on the advances made in Titan's aerosols characterization after 20 years of research, taking into account that we have no direct information on them (Coll et al., Adv. Space Res., subm.).
