The composition distributions of the supernova ejecta are adopted from 3.3, 4, 6, and 8 solar mass He star models. The supernova ejecta are divided into seven layers: Ni, Si/S, O/Si, O/Ne, O/C or C/O, He/C, and He/N layers. We consider the mixing of seven layers and seek the mixing ratios of the mixtures reproducing the isotopic ratios for six SiC type X grains and four low density graphite grains. We find the mixtures reproducing five isotopic ratios of three SiC type X grains and three low density graphite grains. The main composition of the mixtures is the He/N layer. In order to reproduce Al-26/Al-27 and Ti-44/Ti-48 larger than 0.1, the Ni layer should be included. However, too much mixing ratio of the Ni layer reduces the C/O ratio of the mixtures. The O/Si layer should not be contained to avoid the excess of Si-30.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0063350014","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":"東北大学 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":"Tohoku 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":"吉田, 敬"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yoshida, Takashi","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"超新星放出物","subitem_subject_scheme":"Other"},{"subitem_subject":"恒星進化","subitem_subject_scheme":"Other"},{"subitem_subject":"同位体比","subitem_subject_scheme":"Other"},{"subitem_subject":"混合比","subitem_subject_scheme":"Other"},{"subitem_subject":"隕石母天体","subitem_subject_scheme":"Other"},{"subitem_subject":"隕石組成","subitem_subject_scheme":"Other"},{"subitem_subject":"核反応","subitem_subject_scheme":"Other"},{"subitem_subject":"ヘリウム星","subitem_subject_scheme":"Other"},{"subitem_subject":"supernova ejecta","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"stellar evolution","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"isotope ratio","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"mixing ratio","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"meteorite parent body","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"meteoritic composition","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"nuclear reaction","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"helium star","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":"Supernova seven-layer mixing models to reproduce isotopic ratios of presolar grains","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Supernova seven-layer mixing models to reproduce isotopic ratios of presolar grains","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":"20529","relation_version_is_last":true,"title":["Supernova seven-layer mixing models to reproduce isotopic ratios of presolar grains"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T03:49:00.095398+00:00"}
