The vapor cloud can accelerate the planetary atmosphere to escape velocity and cause the loss of atmosphere. It is called impact erosion. Investigated was the impact erosion in ideal adiabatic atmosphere by computational means and compared the results with those obtained from a simple model proposed by Vickery and Melosh (1990). The strong shock is produced in the atmosphere and propagates vertically as predicted by Newman et al. (1999). On the other hand, horizontal flow blows the atmosphere away from the impact point. This flow pattern is not reported by any previous studies. Due to such a horizontal flow, the amount of the atmospheric loss is larger than that predicted by the simple model.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0047898016","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":"東京大学 大学院理学系研究科"},{"subitem_text_value":"東京大学 大学院理学系研究科"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"University of Tokyo Graduate School of Science"},{"subitem_text_language":"en","subitem_text_value":"University of Tokyo 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":"濱野, 景子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"阿部, 豊"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hamano, Keiko","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Abe, Yutaka","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"衝撃侵食","subitem_subject_scheme":"Other"},{"subitem_subject":"数値シミュレーション","subitem_subject_scheme":"Other"},{"subitem_subject":"珪酸塩","subitem_subject_scheme":"Other"},{"subitem_subject":"蒸気雲","subitem_subject_scheme":"Other"},{"subitem_subject":"惑星重力","subitem_subject_scheme":"Other"},{"subitem_subject":"流れ分布","subitem_subject_scheme":"Other"},{"subitem_subject":"惑星大気","subitem_subject_scheme":"Other"},{"subitem_subject":"脱出速度","subitem_subject_scheme":"Other"},{"subitem_subject":"impact erosion","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"numerical simulation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"silicate","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"vapor cloud","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"planetary gravitation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"flow distribution","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"planetary atmosphere","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"escape velocity","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":"Numerical simulation of impact erosion: Comparison with a simple model","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Numerical simulation of impact erosion: Comparison with a simple model","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["1792","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"20594","relation_version_is_last":true,"title":["Numerical simulation of impact erosion: Comparison with a simple model"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T03:48:03.947102+00:00"}
