Temporal variation of disk composition is simulated by performing numerical calculation for advective-diffusion in accretion disk and taking into account the effects of preferential dust migration and evaporation of H2O ice and organics. The estimated time scale of compositional evolution is consistent with chronological suggestion for the interval between formation of CAIs (Ca and Al rich Inclusions) and chondrules. If the disk accretion rate rapidly decays, C/O ratio of innermost disk significantly changes. A reduced environment which can produce SiC would be formed at the inner edge of disk. Heterogeneous recycling of produced SiC would have controlled the redox state of chondrites.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0063350035","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":"北海道大学 大学院理学研究科"},{"subitem_text_value":"北海道大学 大学院理学研究科"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Hokkaido University Graduate School of Science"},{"subitem_text_language":"en","subitem_text_value":"Hokkaido University Graduate School of Science"}]},"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":"福井, 隆"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"倉本, 圭"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Fukui, Takashi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kuramoto, Kiyoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"原始惑星系円盤","subitem_subject_scheme":"Other"},{"subitem_subject":"原始惑星","subitem_subject_scheme":"Other"},{"subitem_subject":"降着円盤","subitem_subject_scheme":"Other"},{"subitem_subject":"酸素同位体","subitem_subject_scheme":"Other"},{"subitem_subject":"同位体比","subitem_subject_scheme":"Other"},{"subitem_subject":"太陽星雲","subitem_subject_scheme":"Other"},{"subitem_subject":"炭素","subitem_subject_scheme":"Other"},{"subitem_subject":"コンドライト","subitem_subject_scheme":"Other"},{"subitem_subject":"コンドルール","subitem_subject_scheme":"Other"},{"subitem_subject":"惑星進化","subitem_subject_scheme":"Other"},{"subitem_subject":"酸化還元状態","subitem_subject_scheme":"Other"},{"subitem_subject":"同位体濃縮","subitem_subject_scheme":"Other"},{"subitem_subject":"protoplanetary disk","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"protoplanet","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"accretion disk","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"oxygen isotope","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"isotope ratio","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"solar nebula","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"carbon","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"chondrite","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"chondrule","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"planetary evolution","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"redox state","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"isotopic enrichment","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":"Evolution of oxygen isotopic composition and C/O ratio at late stage of protoplanetary accretion disk","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Evolution of oxygen isotopic composition and C/O ratio at late stage of protoplanetary accretion disk","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["1791","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"20550","relation_version_is_last":true,"title":["Evolution of oxygen isotopic composition and C/O ratio at late stage of protoplanetary accretion disk"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T03:48:41.365534+00:00"}
