In the classical region (from semimajor axis a 42 AU to 48 AU), several features can be observed such as an unexpected excitation in both eccentricity e and inclination i, dynamically distinct populations and the presence of chaotic regions. The latter is usually associated with mean motion resonances with Neptune. For instance, there is evidence of a decrease of the number of objects around the 7:4 mean motion resonance (a approximately equal to 43.7 AU). In order to better understand these characteristics pointed above, numerical simulation results are presented. Test particles located initially between a = 43.0 AU and 44.4 AU with the relation of 0 less than e less than 0.30 and inclinations up to 15 deg were integrated for 2 Gy under the gravitational influence of the four giant planets. The simulated bodies seem to avoid staying locked in resonance creating a swallow gap. Inside the resonance region there is a tendency of objects with moderate to high inclinations. A chaotic diffusion experiment was also conducted to investigate the resonance dynamics. Inclination dependence and resonance dynamics in the classical region demonstrate that it is continuously evolving, causing non-negligible mixing of bodies with different inclinations.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0046650041","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":"神戸大学 大学院自然科学研究科"},{"subitem_text_value":"神戸大学 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":"Kobe University Graduate School of Science and Technology"},{"subitem_text_language":"en","subitem_text_value":"Kobe University Graduate School of 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":"Lykawka, Patryk Sofia"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"向井, 正"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Lykawka, Patryk Sofia","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Mukai, Tadashi","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"古典transneptunianベルト","subitem_subject_scheme":"Other"},{"subitem_subject":"力学的構造","subitem_subject_scheme":"Other"},{"subitem_subject":"7:4平均運動共鳴","subitem_subject_scheme":"Other"},{"subitem_subject":"外側太陽系","subitem_subject_scheme":"Other"},{"subitem_subject":"数値シミュレーション","subitem_subject_scheme":"Other"},{"subitem_subject":"原始惑星","subitem_subject_scheme":"Other"},{"subitem_subject":"海王星","subitem_subject_scheme":"Other"},{"subitem_subject":"降着","subitem_subject_scheme":"Other"},{"subitem_subject":"classical transneptunian belt","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"dynamical structure","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"7:4 mean motion resonance","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"outer solar system","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"numerical simulation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"protoplanet","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Neptune","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"accretion","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":"The 7:4 mean motion resonance and dynamical structures in the classical transneptunian belt","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"The 7:4 mean motion resonance and dynamical structures in the classical transneptunian belt","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["1793","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"20690","relation_version_is_last":true,"title":["The 7:4 mean motion resonance and dynamical structures in the classical transneptunian belt"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T03:46:37.804181+00:00"}
