We propose that this segregation may be caused by a simple and unexplored effect: pebbles accreting onto the asteroid rebound from boulders, but sink into pebbly regions. By number, overwhelmingly more particles on Itokawa are pebbles, and collisions involving these pebbles must unavoidably cause pebbly regions to grow. We carry out experiments and simulations that demonstrate that this mechanism of size sorting based on simple counting of grains produces strong lateral segregation that reliably obeys an analytic formula.","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"American Physical Society"}]},"item_10001_relation_13":{"attribute_name":"PubMedNo.","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:pmid/28368621","subitem_relation_type_select":"PMID"}}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1103/PhysRevLett.118.111101","subitem_relation_type_select":"DOI"}}]},"item_10001_relation_17":{"attribute_name":"Related site","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.118.111101","subitem_relation_type_select":"URI"}}]},"item_10001_rights_15":{"attribute_name":"Rights","attribute_value_mlt":[{"subitem_rights":"© 2017 American Physical Society."}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0031-9007","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"1079-7114","subitem_source_identifier_type":"ISSN"}]},"item_10001_version_type_20":{"attribute_name":"Author's flag","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-05-11"}],"displaytype":"detail","filename":"PhysRevLett.118.111101.pdf","filesize":[{"value":"2.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"PhysRevLett.118.111101","url":"https://oist.repo.nii.ac.jp/record/383/files/PhysRevLett.118.111101.pdf"},"version_id":"8e05a33e-c7b7-475b-9b05-2aead8f613ad"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Size Sorting on the Rubble-Pile Asteroid Itokawa","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Size Sorting on the Rubble-Pile Asteroid Itokawa","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"27","path":["16","30"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-05-11"},"publish_date":"2018-05-11","publish_status":"0","recid":"383","relation_version_is_last":true,"title":["Size Sorting on the Rubble-Pile Asteroid Itokawa"],"weko_creator_id":"27","weko_shared_id":27},"updated":"2023-06-26T12:07:02.036447+00:00"}
