All manual work was done in 1976–1982 as part of 3 theses works but fundamentally new data interpretation was reached within the last three years. From the CI1 meteorite Orgueil, we are able to separate 1.4 per mill of material containing supernova related noble gases He, Ne and Ar as well as P. We separate minerals using essentially density gradient centrifugation followed by stepwise heating noble gas analysis. Our procedure loses nearly no material and is in sharp contrast to the otherwise used dissolution of >99% of material to obtain single presolar grains (Anders and Zinner, 1993). Our method safeguards minerals considerably more fragile than SiC or TiC presolar grains, such as apatite, Mg-Al-spinel, graphite clusters and even apatite coated graphite clusters. We find graphite, apatite and Mg-Al-spinel containing highly anomalous noble gases. For the first time, apatite, containing anomalous Ar with an isotope ratio for 38Ar/36Ar of 0.35, twice the normal ratio, is reported. Such a ratio is produced by a 20 solar mass type II supernova in the C-O-Ne-burning shell. Unmatched pure Ne-E from 22Na measured in the same samples sets the timeframe for this interaction to a maximum of only a few years.","subitem_description_type":"Abstract"}]},"item_10001_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"我々は低温の星間ダストとII型超新星爆発で放出されたガスとが相互作用した後の、太陽系進化の最初期のデータを示す。我々はオルゲーユCIコンドライトから超新星に由来する希ガスやリンを含む1.4パーミルの物質の分離に成功した。我々は密度勾配を利用した遠心分離および段階加熱による希ガス分析によってこのような物質を分離した。プレソーラー粒子を分離する他の方法とは異なり、我々の方法ではほとんど物質は失われず、破壊されやすい物質も保持される。我々は非常に特異な希ガスを含むグラファイト、アパタイト、およびスピネルを発見した。38Ar/36Ar比が0.35という特異なアルゴンを含むアパタイトの報告はこれが初めてである。そのような組成をもつアルゴンは太陽の20倍の質量を持つII型超新星の炭素・酸素・ネオン燃焼核において合成される。同じ試料に含まれる22Naの壊変に由来する純粋なNe-E成分から、この相互作用の時間スケールは最長でわずか2,3年に制約される。","subitem_description_type":"Other"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1016/j.polar.2016.12.002"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://dx.doi.org/10.1016/j.polar.2016.12.002","subitem_relation_type_select":"DOI"}}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18739652","subitem_source_identifier_type":"ISSN"}]},"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":"Jungck, Matthias H.A.","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"55712","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Niederer, Franz R.","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"55713","nameIdentifierScheme":"WEKO"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Supernova","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Presolar chondritic dust","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Isotope anomalies","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Early Solar system","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Mineral separation","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"From supernova to Solar System: Few years only; first Solar System components apatite and spinel determined","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"From supernova to Solar System: Few years only; first Solar System components apatite and spinel determined"},{"subitem_title":"From supernova to Solar System: Few years only; first Solar System components apatite and spinel determined","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"36","path":["1758"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-02-28"},"publish_date":"2017-02-28","publish_status":"0","recid":"14033","relation_version_is_last":true,"title":["From supernova to Solar System: Few years only; first Solar System components apatite and spinel determined"],"weko_creator_id":"36","weko_shared_id":-1},"updated":"2023-07-25T15:26:09.623003+00:00"}
