A planet excites two density waves on both sides of the planet orbit due to Lindblad resonances. The outer density wave exerts a negative torque on the planet while the inner density wave exerts a positive torque. The sum of the two torque gives the net torque on the planet. As a first step, one of the torques (one-side torque) is examined in the present study. In previous studies of density waves, the isothermal equation of state has been assumed. In this study, solving the energy equation in the linear calculation, the effect of energy transfer on the wave excitation is examined. In protoplanetary disks, the energy is transferred by radiation and the radiative transfer is governed by dust opacity. At the stage of planet formation, the dust opacity is expected to be sufficiently low because of dust growth and planetesimal formation. Thus an optically thin gaseous disk is assumed. The efficiency of radiative transfer increases with the amount of dust in optically thin disks. The amount of dust is considered as a parameter and the one-side torque on a planet is calculated. Due to radiative transfer, the values of the one-side torque is deviated only by about 10 percent from the isothermal case. However, it is also found that the gas in the Hill sphere of the planet has a large contribution on the one-side torque. This large contribution in the Hill sphere may change the net torque sufficiently.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0046650001","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":"東京工業大学 理学部　地球惑星科学科"},{"subitem_text_value":"東京工業大学 理学部　地球惑星科学科"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Tokyo Institute of Technology Department of Earth and Planetary Sciences, School of Science"},{"subitem_text_language":"en","subitem_text_value":"Tokyo Institute of Technology Department of Earth and Planetary Sciences, 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":"伊東, 真史"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"田中, 秀和"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ito, Masafumi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tanaka, Hidekazu","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"重力場","subitem_subject_scheme":"Other"},{"subitem_subject":"原始惑星ディスク","subitem_subject_scheme":"Other"},{"subitem_subject":"惑星","subitem_subject_scheme":"Other"},{"subitem_subject":"放射移動","subitem_subject_scheme":"Other"},{"subitem_subject":"数値解析","subitem_subject_scheme":"Other"},{"subitem_subject":"波動励起","subitem_subject_scheme":"Other"},{"subitem_subject":"放射冷却","subitem_subject_scheme":"Other"},{"subitem_subject":"温度分布","subitem_subject_scheme":"Other"},{"subitem_subject":"gravitational field","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"protoplanetary disk","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"planet","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"radiative transfer","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"numerical analysis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"wave excitation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"radiant cooling","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"temperature distribution","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":"Gravitational interaction between a planet and an optically thin protoplanetary disk","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Gravitational interaction between a planet and an optically thin protoplanetary disk","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":"20650","relation_version_is_last":true,"title":["Gravitational interaction between a planet and an optically thin protoplanetary disk"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T03:47:14.137868+00:00"}
