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."}],"language":[{"iso":"eng"}],"oa":"1","doi":"10.1051/0004-6361/201730801","intvolume":"       608","publication_status":"published","publisher":"EDP Sciences","keyword":["tet_topic_scattering"],"type":"journal_article","urn":"35230","article_type":"original","ddc":["530"],"_id":"3523"}
