Light scattering by cometary dust particles analogs
Résumé
Polarimetric observations of cometary comae may be used to infer dust properties through experimental simulations. Mixtures of fluffy silicates and carbon were successfully studied and confirmed the results from remote observations. New samples are proposed to better represent the particles observed in comets with important dust activity or less active comets without important jet emissions or before perihelion. Different organics, which can be eventually heated, are also studied. The samples are lifted in lowdensity cloud in the PROGRA2 light scattering experiment.
