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."}],"doi":"10.1051/0004-6361/201730801","volume":608,"urn":"35230","ddc":["530"],"year":"2017","publication_identifier":{"issn":["0004-6361","1432-0746"]},"intvolume":" 608","_id":"3523","status":"public","author":[{"full_name":"Dogra, Shraddha","last_name":"Dogra","first_name":"Shraddha"},{"last_name":"Grynko","full_name":"Grynko, Yevgen","first_name":"Yevgen","id":"26059"},{"full_name":"Zubko, Evgenij","last_name":"Zubko","first_name":"Evgenij"},{"last_name":"Förstner","full_name":"Förstner, Jens","id":"158","orcid":"0000-0001-7059-9862","first_name":"Jens"}],"date_created":"2018-07-10T10:19:01Z","publication":"Astronomy & Astrophysics","file_date_updated":"2018-09-03T14:05:33Z","type":"journal_article","page":"A20","user_id":"158","publisher":"EDP Sciences","citation":{"bibtex":"@article{Dogra_Grynko_Zubko_Förstner_2017, title={Radar backscattering from a large-grain cometary coma: numerical simulation}, volume={608}, DOI={10.1051/0004-6361/201730801}, journal={Astronomy & Astrophysics}, publisher={EDP Sciences}, author={Dogra, Shraddha and Grynko, Yevgen and Zubko, Evgenij and Förstner, Jens}, year={2017}, pages={A20} }","ama":"Dogra S, Grynko Y, Zubko E, Förstner J.
