We apply the discrete dipole approximation method and a model of random irregular particles. Our results confirm water ice composition of the cm-sized chunks detected by the NASA Deep Impact space probe in the vicinity of the nucleus of Comet 103P/Hartley 2. The index of the power-law size distribution in this case can be constrained to the range n ≈ 3.3–4.3. For the other considered comets the circular polarization ratio can be reproduced with variations of the power index between 2 and 5."}],"_id":"3523","publisher":"EDP Sciences","author":[{"full_name":"Dogra, Shraddha","last_name":"Dogra","first_name":"Shraddha"},{"id":"26059","full_name":"Grynko, Yevgen","last_name":"Grynko","first_name":"Yevgen"},{"last_name":"Zubko","first_name":"Evgenij","full_name":"Zubko, Evgenij"},{"first_name":"Jens","last_name":"Förstner","orcid":"0000-0001-7059-9862","id":"158","full_name":"Förstner, Jens"}],"department":[{"_id":"61"}]}
