This depletion of sub-micrometer sized grains makes the 10-micrometer silicate feature disappear in the model SED (Spectral Energy Distribution), which is inconsistent with disk observations. The collisional disruption of grains may produce sub-micrometer sized grains. In the present study, we propose the effect of H2O evaporation as an alternative mechanism producing sufficient sub-micron grains. The H2O ice in grains evaporates at the disk surface because of its high temperature compared with the disk interior. Then, grains break up into silicate monomers. This break-up mechanism would also have an important effect on the disk temperature and configuration as well as the 10-micrometer silicate feature.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0063350011","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":"北海道大学低温科学研究所"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Institute of Low Temperature Science, Hokkaido 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":"田中, 秀和"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tanaka, Hidekazu","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"原始惑星系円盤","subitem_subject_scheme":"Other"},{"subitem_subject":"惑星進化","subitem_subject_scheme":"Other"},{"subitem_subject":"粒子衝突","subitem_subject_scheme":"Other"},{"subitem_subject":"ダスト微粒子","subitem_subject_scheme":"Other"},{"subitem_subject":"蒸発","subitem_subject_scheme":"Other"},{"subitem_subject":"水","subitem_subject_scheme":"Other"},{"subitem_subject":"ケイ酸塩","subitem_subject_scheme":"Other"},{"subitem_subject":"微惑星","subitem_subject_scheme":"Other"},{"subitem_subject":"おうし座T型星","subitem_subject_scheme":"Other"},{"subitem_subject":"粒度分布","subitem_subject_scheme":"Other"},{"subitem_subject":"protoplanetary disk","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"planetary evolution","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"particle collision","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"dust grain","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"evaporation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"water","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"silicate","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"planetesimal","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"T Tauri star","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"particle size 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":"Dust growth and H2O evaporation in protoplanetary disks","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Dust growth and H2O evaporation in protoplanetary disks","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":"20526","relation_version_is_last":true,"title":["Dust growth and H2O evaporation in protoplanetary disks"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T03:49:02.746889+00:00"}
