Radiative properties, including extinction efficiency, single-scattering albedo, and asymmetry of haze particles, using the refractive indices derived on PAMPRE and COSmIC Titan and Exoplanet haze analogs. The calculations account for the simple spherical particles (solid curves) and fractal aggregates of spherical monomers (dashed curves) expected in hazy planetary atmospheres. Two different morphologies are shown. A first morphology similar to Titan hazes is considered with D_f=2, N_m=3000, and r_m=50 nm for the three different haze analogs shown (blue, red, and green curves). A second morphology representing exoplanet hazes is shown (gray curves) only for the PAMPRE Exoplanet 2 analog using D_f=2, N_m=3 × 10⁶, and r_m= 5 nm. The extinction efficiency here is defined by the extinction cross section divided by the surface area of the sphere of equivalent volume.
