When small bodies or dusts impact those primordial bodies, strength and internal structure, including porosity, of the target bodies should play important roles in the process of penetration. However, the penetration mechanism has not been fully understood yet. We fabricated high-porosity sintered targets consisting of soda-lime acid silicate hollow glass beads. The sintered targets had porosity of about 94 % and the bulk density of ca.0.14 g/cm3. We conducted impact experiments at high velocity at ISAS using a two-stage light-gas gun and a high speed camera. The impact velocities were ca.2.5, 4.0, 7.0km/s. The penetration depth and track morphology are examined by X-ray micro tomography at Osaka University. In order to discuss the penetration depth, we got data of the deceleration of the projectile and consider a model in which the largest fragment of the projectile decelerates due to a drag force proportional to the square of the velocity and determines the track length. Our model roughly reproduces the track length of the experiment.","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: AA0065390019","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所 (JAXA)(ISAS)"}]},"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_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":"神戸大学大学院理学研究科地球惑星科学専攻"},{"subitem_text_value":"神戸大学大学院理学研究科地球惑星科学専攻"},{"subitem_text_value":"宇宙航空研究開発機構宇宙科学研究所 (JAXA)(ISAS)"},{"subitem_text_value":"宇宙航空研究開発機構宇宙科学研究所 (JAXA)(ISAS)"},{"subitem_text_value":"大阪大学大学院理学研究科宇宙地球科学専攻"},{"subitem_text_value":"大阪大学大学院理学研究科宇宙地球科学専攻"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department of Earth and Planetary Sciences, Graduate School of Science, Kobe University"},{"subitem_text_language":"en","subitem_text_value":"Department of Earth and Planetary Sciences, Graduate School of Science, Kobe University"},{"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":"Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS)"},{"subitem_text_language":"en","subitem_text_value":"Department of Earth and Space Science, Graduate School of Science, Osaka University"},{"subitem_text_language":"en","subitem_text_value":"Department of Earth and Space Science, Graduate School of Science, Osaka University"}]},"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":"中村, 昭子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"長谷川, 直"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"黒澤, 耕介"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"土山, 明"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Okamoto, T.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nakamura, Akiko M.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hasegawa, Sunao","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kurosawa, Kosuke","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ikezaki, K.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tsuchiyama, Akira","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":"Experimental Study for Surface Structure of Porous Small Bodies : Dust Penetration Depth","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Experimental Study for Surface Structure of Porous Small Bodies : Dust Penetration Depth","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["1785","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"20304","relation_version_is_last":true,"title":["Experimental Study for Surface Structure of Porous Small Bodies : Dust Penetration Depth"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T03:52:08.604614+00:00"}
