These observations show that ITOKAWA is a rubble-pile asteroid which consists of the rocks piled up by universal gravity. Its unique shape and regolith distribution are caused by composition of universal gravity, friction, centrifugal force by spin and impacts. These impacts are given by collisions of small falling particles. In this study, the behaviors of various size particles of a rubble-pile asteroid in the space are analyzed by numerical simulations using multi-particle model. We focus the Brazil-Nut effect which is generally known as the phenomenon that causes the larger particles to rise to the top of the shaken granular mixtures in a container and the Arch effect which has an important role in that effect.","subitem_description_type":"Other"}]},"item_5_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: カラー図版あり","subitem_description_type":"Other"}]},"item_5_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0064733010","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構宇宙科学研究本部"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11567475","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学大学院工学系研究科航空宇宙工学専攻"},{"subitem_text_value":"宇宙航空研究開発機構月惑星探査推進グループ"},{"subitem_text_value":"宇宙航空研究開発機構月惑星探査推進グループ"},{"subitem_text_value":"宇宙航空研究開発機構月惑星探査推進グループ"},{"subitem_text_value":"宇宙航空研究開発機構月惑星探査プログラムグループ"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department of Aeronautics and Astronautics, School of Engineering, University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"JAXA Space Exploration Center, Japan Aerospace Exploration Agency (JAXA)(JSPEC)"},{"subitem_text_language":"en","subitem_text_value":"JAXA Space Exploration Center, Japan Aerospace Exploration Agency (JAXA)(JSPEC)"},{"subitem_text_language":"en","subitem_text_value":"JAXA Space Exploration Center, Japan Aerospace Exploration Agency (JAXA)(JSPEC)"},{"subitem_text_language":"en","subitem_text_value":"Lunar and Planetary Exploration Program Group, Japan Aerospace Exploration Agency (JAXA)(JSPEC)"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"三和, 裕一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"矢野, 創"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"森本, 睦子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"森, 治"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"川口, 淳一郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Miwa, Yuichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yano, Hajime","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Morimoto, Mutsuko Y.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Mori, Osamu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kawaguchi, Junichiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"多粒子数値解析を用いたラブルパイル小惑星の構造に対する考察","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"多粒子数値解析を用いたラブルパイル小惑星の構造に対する考察"}]},"item_type_id":"5","owner":"1","path":["1555","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"7384","relation_version_is_last":true,"title":["多粒子数値解析を用いたラブルパイル小惑星の構造に対する考察"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T07:40:20.819401+00:00"}
