The ejection velocity of fine fragments formed by the jetting process near the impact point was determined to be 1.7-2.9 times as large as the impact velocity irrespective of the target size and the impact velocity. The ejection velocity of fragments at the rear side of the target (V(sub e)) varied with distance from the impact point according to a power law relation, V(sub e) = V(sub a)(l/D)(exp -n), where V(sub a) is the antipodal velocity, l and D are the distance and the target diameter, and n is 1.5-2.0. V(sub a) depends on the specific energy (Q) at a constant mass ratio (m(sub p)/M(sub t) = 0.13) and the empirical dependence is written by V(sub a) = 0.35 x Q(exp 0.52).","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0063352010","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":"北海道大学低温科学研究所"},{"subitem_text_value":"北海道大学低温科学研究所"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Institute of Low Temperature Science, Hokkaido University"},{"subitem_text_language":"en","subitem_text_value":"Institute of Low Temperature Science, Hokkaido 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":"荒川, 政彦"}],"nameIdentifiers":[{"nameIdentifier":"433081","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"比嘉, 道也"}],"nameIdentifiers":[{"nameIdentifier":"433082","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Arakawa, Masahiko","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"433083","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Higa, Michiya","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"433084","nameIdentifierScheme":"WEKO"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"外部太陽系","subitem_subject_scheme":"Other"},{"subitem_subject":"衝突速度","subitem_subject_scheme":"Other"},{"subitem_subject":"破砕","subitem_subject_scheme":"Other"},{"subitem_subject":"氷","subitem_subject_scheme":"Other"},{"subitem_subject":"氷衛星","subitem_subject_scheme":"Other"},{"subitem_subject":"速度分布","subitem_subject_scheme":"Other"},{"subitem_subject":"脱出速度","subitem_subject_scheme":"Other"},{"subitem_subject":"衝撃波","subitem_subject_scheme":"Other"},{"subitem_subject":"微惑星","subitem_subject_scheme":"Other"},{"subitem_subject":"outer solar system","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"impact velocity","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"fragmentation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"ice","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"icy satellite","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"velocity distribution","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"escape velocity","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"shock wave","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"planetesimal","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":"Measurements of ejection velocities in collisional disruption of ice spheres","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Measurements of ejection velocities in collisional disruption of ice spheres","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"38377","relation_version_is_last":true,"title":["Measurements of ejection velocities in collisional disruption of ice spheres"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T22:41:34.420070+00:00"}
