In our previous studies, we carried out laser ablation experiments within gas mixtures to simulate chemical reactions between impact-induced CN radicals and an ambient atmosphere after oblique impacts. We found that a large amount of cyanides are produced even within CO2-rich ambient gases. However, it is not clear how well laser-induced vapor plumes simulate vapor plume due to aerodynamic ablation of high-speed fragments from oblique impacts. In this study, we conducted hypervelocity oblique impact experiments in an N2 gas to compare the thermodynamic states of laser-ablation vapor and real impacts. Using high-speed spectroscopic measurements, the vibrational states and translational-rotational temperatures of impact-induced CN radicals are estimated. We found that the translational-rotational temperature of CN and C2 by impacts at ca.7 km/s of impact velocity was close to that by laser ablation with 9.0 x 10(exp 8)W/cm2 of laser intensity Experimental results indicate that laser ablation can simulate aerodynamic ablation process due to oblique impacts including vibrational non-equilibrium. This suggests that cyanide production efficiency estimated by laser ablation can apply to impact processes. Thus, impacts of C-rich meteorites may cause significant concentration of cyanide on the early Earth.","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"},{"subitem_description":"形態: CD-ROM1枚","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"},{"subitem_description":"Note: One CD-ROM","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0064739034","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":"AA12268968","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学大学院新領域創成科学研究科複雑理工学専攻"},{"subitem_text_value":"東京大学大学院新領域創成科学研究科複雑理工学専攻"},{"subitem_text_value":"宇宙航空研究開発機構宇宙科学研究本部"},{"subitem_text_value":"総合研究大学院大学物理科学研究科"},{"subitem_text_value":"千葉工業大学惑星探査研究センター"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department of Complexity Science and Engineering, Graduate School of Frontier Science, Universityof Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Department of Complexity Science and Engineering, Graduate School of Frontier Science, Universityof Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS)"},{"subitem_text_language":"en","subitem_text_value":"School of Physical Sciences, The Graduate University for Advanced Studies"},{"subitem_text_language":"en","subitem_text_value":"Planetary Exploration Research Center, Chiba Institute of 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":"黒澤, 耕介"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"杉田, 精司"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"長谷川, 直"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"長岡, 洋一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"松井, 孝典"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kurosawa, Kosuke","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sugita, Seiji","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hasegawa, Sunao","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nagaoka, Yoichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Matsui, Takafumi","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"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":"Spectroscopic observations on CN radical production process due to oblique impacts: Thermodynamic states of impact- and laser-induced CN radicals","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Spectroscopic observations on CN radical production process due to oblique impacts: Thermodynamic states of impact- and laser-induced CN radicals","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["1787","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"20378","relation_version_is_last":true,"title":["Spectroscopic observations on CN radical production process due to oblique impacts: Thermodynamic states of impact- and laser-induced CN radicals"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T03:51:05.307290+00:00"}
