We confirm that the following dust circulation mechanism will be realized: at the inner edge of the disk, the infalling dust aggregates partially evaporate and break up into fine grains, which are stirred up to the upper irradiated region by magnetorotational instability and are blown outward by the radiation pressure. Most of the blowing grains reenter into the disk within approximately 1 AU and settle to the midplane, joining inwardly-migrating dust aggregates. We find that in the shadowed region of the disk the outflow mass flux in the surface layer is comparable to the inflow mass flux in the disk interior. Dust circulation occurs efficient in the shadowed region if the turbulent intensity in the innermost region of the disk and the stellar luminosity are sufficient higher. In a steady state, the surface density distribution of the dust is enhanced by dust circulation in the inner shadowed region. Therefore, the enhanced abundance of the dust may cause gravitational instability for planetesimal formation.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0063350034","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":"名古屋大学 大学院環境学研究科"},{"subitem_text_value":"名古屋大学 大学院環境学研究科"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Nagoya University Graduate School of Environmental Studies"},{"subitem_text_language":"en","subitem_text_value":"Nagoya University Graduate School of Environmental Studies"}]},"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":"藤原, 大輔"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"渡邊, 誠一郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Fujiwara, Daisuke","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Watanabe, Seiichiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"宇宙塵","subitem_subject_scheme":"Other"},{"subitem_subject":"放射圧","subitem_subject_scheme":"Other"},{"subitem_subject":"計算機シミュレーション","subitem_subject_scheme":"Other"},{"subitem_subject":"原始惑星系円盤","subitem_subject_scheme":"Other"},{"subitem_subject":"原始惑星","subitem_subject_scheme":"Other"},{"subitem_subject":"乱流","subitem_subject_scheme":"Other"},{"subitem_subject":"循環","subitem_subject_scheme":"Other"},{"subitem_subject":"恒星光度","subitem_subject_scheme":"Other"},{"subitem_subject":"密度分布","subitem_subject_scheme":"Other"},{"subitem_subject":"惑星間塵","subitem_subject_scheme":"Other"},{"subitem_subject":"重力不安定性","subitem_subject_scheme":"Other"},{"subitem_subject":"cosmic dust","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"radiation pressure","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"computerized simulation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"protoplanetary disk","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"protoplanet","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"turbulence","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"circulation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"stellar luminosity","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"density distribution","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"interplanetary dust","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"gravitational instability","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":"Dust circulation by radiation pressure in protoplanetary disks with puffed up inner rim","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Dust circulation by radiation pressure in protoplanetary disks with puffed up inner rim","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":"20549","relation_version_is_last":true,"title":["Dust circulation by radiation pressure in protoplanetary disks with puffed up inner rim"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T03:48:42.160085+00:00"}
