Cometary dust environment modelling is required to make predictions for the European Space Agency's Rosetta mission. Following results from pre-planetary dust aggregation experiments both on Earth and in space (CODAG), we have developed a code to generate and study the morphological properties of dust chains characterized by low fractal mass dimension. We analysed the scattering properties of these chains, comparing their behaviour with the dust scattering properties seen in cometary comae. We also made a comparison between low fractal dimension and Ballistic Cluster-Cluster aggregates. Initial results and future prospects are here described.

Abstract
Cometary dust environment modelling is required to make predictions for the European Space Agency's Rosetta mission. Following results from pre-planetary dust aggregation experiments both on Earth and in space (CODAG), we have developed a code to generate and study the morphological properties of dust chains characterized by low fractal mass dimension. We analysed the scattering properties of these chains, comparing their behaviour with the dust scattering properties seen in cometary comae. We also made a comparison between low fractal dimension and Ballistic Cluster-Cluster aggregates. Initial results and future prospects are here described.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
