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."}],"publisher":"EDP Sciences","file_date_updated":"2018-09-03T14:05:33Z","keyword":["tet_topic_scattering"],"article_type":"original","date_created":"2018-07-10T10:19:01Z","page":"A20","intvolume":"       608","status":"public","ddc":["530"],"author":[{"last_name":"Dogra","first_name":"Shraddha","full_name":"Dogra, Shraddha"},{"full_name":"Grynko, Yevgen","id":"26059","first_name":"Yevgen","last_name":"Grynko"},{"full_name":"Zubko, Evgenij","last_name":"Zubko","first_name":"Evgenij"},{"id":"158","orcid":"0000-0001-7059-9862","full_name":"Förstner, Jens","last_name":"Förstner","first_name":"Jens"}],"file":[{"file_name":"2017-10 Dogra,Grynko,Zubko,Förstner_Radar backscattering from large scale cometary coma-Numerical simulation_Astronomy and Astrophysics.pdf","creator":"hclaudia","relation":"main_file","file_id":"3903","access_level":"open_access","date_updated":"2018-09-03T14:05:33Z","content_type":"application/pdf","date_created":"2018-08-14T10:17:27Z","file_size":1206283}],"urn":"35230","type":"journal_article","_id":"3523","oa":"1","date_updated":"2022-01-06T06:59:21Z"}
