Morota et al. [2004] have suggested a probable model of evolution of crustal structure and rotation of the early Moon, associated with the heavy asymmetrical bombardment as follows. The preferential bombardment thinned the crust of the leading hemisphere and thickened that of the trailing hemisphere. As a consequence of the redistribution of crustal materials, the axis of the minimum principal moment of inertia shifted toward the west. The Moon was reoriented eastwards with the new minimum axis along the Earth-Moon line. The sequential actions operated continuously and concurrently on the early Moon, so that the Moon was gradually rotated toward the east. Longitudinal distributions of impact basins and crustal thickness models support the scenario. In this paper, we assay whether the heavy asymmetrical bombardment could generate the redistribution of crustal materials enough for the lunar continuous reorientation or not.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0063350020","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":"宇宙航空研究開発機構 宇宙科学研究本部　固体惑星科学研究系"},{"subitem_text_value":"金沢大学 大学院自然科学研究科"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency Department of Planetary Science, Institute of Space and Astronautical Science"},{"subitem_text_language":"en","subitem_text_value":"Kanazawa University Graduate School of Natural Science and 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":"諸田, 智克"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"古本, 宗充"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Morota, Tomokatsu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Furumoto, Muneyoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"月再配向","subitem_subject_scheme":"Other"},{"subitem_subject":"クレータ形成","subitem_subject_scheme":"Other"},{"subitem_subject":"月クレータ","subitem_subject_scheme":"Other"},{"subitem_subject":"月地殻","subitem_subject_scheme":"Other"},{"subitem_subject":"非対称性","subitem_subject_scheme":"Other"},{"subitem_subject":"慣性モーメント","subitem_subject_scheme":"Other"},{"subitem_subject":"超高速衝突","subitem_subject_scheme":"Other"},{"subitem_subject":"小惑星衝突","subitem_subject_scheme":"Other"},{"subitem_subject":"月回転","subitem_subject_scheme":"Other"},{"subitem_subject":"月裏側","subitem_subject_scheme":"Other"},{"subitem_subject":"lunar reorientation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"cratering","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"lunar crater","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"lunar crust","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"asymmetry","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"moment of inertia","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"hypervelocity impact","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"asteroid collision","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"lunar rotation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"lunar far side","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":"Continuous reorientation of the early Moon as a consequence of a leading-trailing asymmetry in the cratering rate","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Continuous reorientation of the early Moon as a consequence of a leading-trailing asymmetry in the cratering rate","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["1791","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"20535","relation_version_is_last":true,"title":["Continuous reorientation of the early Moon as a consequence of a leading-trailing asymmetry in the cratering rate"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T03:48:55.007189+00:00"}
