For the spherical harmonics, up to the 3rd-oder terms are taken into account. The motion is characterized by perturbation from a nominal orbit in every one period. In this study, the nominal orbit is defined by the solution of the two body problem. From the potential, the two-mass body's gravity field consists of two shape effects: an ellipsoidal shape and an asymmetric mass-distribution along the major semiaxis. To see the motion in the real case, the close orbit about Asteroid Itokawa is investigated. Under the condition that the inclination is 90 deg and the orbital period is an integer times slower than the spin rate, only the drift of the argument of latitude appears.","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"}]},"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"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0065115019","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":"AA11567475","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"},{"subitem_text_value":"名古屋大学"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Nagoya 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":"平林, 正稔"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山田, 克彦"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hirabayashi, Masatoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamada, Katsuhiko","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":"THE PRELIMINARY ANALYSIS OF THE PERIODICAL ORBIT AROUND A SMALL ASTEROID MODELED BY THE TWO-MASS MODEL","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"THE PRELIMINARY ANALYSIS OF THE PERIODICAL ORBIT AROUND A SMALL ASTEROID MODELED BY THE TWO-MASS MODEL","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["1553","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"7266","relation_version_is_last":true,"title":["THE PRELIMINARY ANALYSIS OF THE PERIODICAL ORBIT AROUND A SMALL ASTEROID MODELED BY THE TWO-MASS MODEL"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T07:42:09.924478+00:00"}
