Abstract
In the present work, the light-scattering properties of comet Levy 1990XX are studied through simulations using Ballistic Particle-Cluster Aggregation (BPCA) or Ballistic Cluster-Cluster Aggregation (BCCA) aggregates of up to 128 spherical monomers of different compositions (e.g. silicates, carbonaceous materials etc.) and the best-fitting theoretical polarization curve is generated using the SUPERPOSITION T-MATRIX code. The best-fitting refractive indices coming out from the present analysis show silicate behaviour when monomer radius is a m = 0.12 μm and provide excellent results on the maximum and negative degrees of linear polarization at a single wavelength λ = 0.485 μm for BCCA aggregates.
