Principal force on these particles except for gravitational forces from the Sun and planets is solar radiation pressure which involves drag force known as P-R drag. Its force reduces dust's mechanical energy and a dust ends up spiralling in towards the Sun. This behavior of the dust provides the possibility that a dust passing near the Earth can be trapped in a horseshoe orbit by the gravity of the Earth. In this paper, we assume that a dust is trapped in the orbit and calculate distributions of dust's number density and velocity on the orbit. Furthermore, we analyze the possibility that a dust is trapped or not.","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: AA0064733042","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"},{"subitem_text_value":"宇宙航空研究開発機構宇"},{"subitem_text_value":"宇宙航空研究開発機構月惑星探査推進グループ"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"JAXA Space Exploration Center, 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":"元岡, 範純"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"矢野, 創"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"川口, 淳一郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Motooka, Norizumi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yano, Hajime","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":"馬蹄形軌道に捕獲されたダストの密度分布に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"馬蹄形軌道に捕獲されたダストの密度分布に関する研究"}]},"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":"7416","relation_version_is_last":true,"title":["馬蹄形軌道に捕獲されたダストの密度分布に関する研究"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T07:39:51.348437+00:00"}
