Referring to the numerical simulation for dynamical evolution of grains released from 2003EH1, a relation between a radius of survived meteor s (mm) and its lifetime t (yrs) is derived, i.e. log t = 0.23 log s + 7.34. Since there is no information of the past cometary activities of 2003EH1, three models are assumed, i.e. 1) intermittent activity (every 200 years), 2) ordinary continuous activity at every perihelion passage in some interval of the past, and 3) a single split of an asteroid in the past. The size distribution of survived meteors have been determined in each of cases as a form of s(sub -alpha) ds. Finally, it is proposed to search for the dust trail along the orbit of the Quadrantid, as well as a detection of its color. These data will provide a useful tool to confirm the size distribution of survived meteors, and consequently these results would reply on the question how 2003EH1 has supplied the meteors forming the current Quadrantid meteor stream.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0047898058","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/ISAS)"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"兵庫県立有馬高校"},{"subitem_text_value":"神戸大学 大学院自然科学研究科"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Hyogo Prefectural Arima Senior High School"},{"subitem_text_language":"en","subitem_text_value":"Kobe University Graduate School of Science and Technology"}]},"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":"谷川, 智康"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"向井, 正"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tanigawa, Tomoyasu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Mukai, Tadashi","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Quadrantid流星跡","subitem_subject_scheme":"Other"},{"subitem_subject":"小惑星","subitem_subject_scheme":"Other"},{"subitem_subject":"彗星","subitem_subject_scheme":"Other"},{"subitem_subject":"近日点","subitem_subject_scheme":"Other"},{"subitem_subject":"数値解析","subitem_subject_scheme":"Other"},{"subitem_subject":"サイズ分布","subitem_subject_scheme":"Other"},{"subitem_subject":"太陽放射圧","subitem_subject_scheme":"Other"},{"subitem_subject":"重力","subitem_subject_scheme":"Other"},{"subitem_subject":"Quadrantid meteor stream","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"asteroid","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"comet","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"perihelion","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"numerical analysis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"size distribution","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"solar radiation pressure","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"gravitation","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"2003EH1 and Quadrantids","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"2003EH1 and Quadrantids","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["1792","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"20636","relation_version_is_last":true,"title":["2003EH1 and Quadrantids"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T03:47:25.749292+00:00"}
