We find that the spectral fitting is significantly improved for about one third of data and that the derived q-value changes from 0.67 to 0.85 in accordance with the spectral evolution from the horizontal branch (HB) to the flaring branch (FB) via the normal branch (NB). Two positive and negative correlations are found between the inner disk radius (R_in) and q, and between R_in and the inner disk temperature (T_in). Possible new interpretations regarding the branch behavior of C_yg X-2 are discussed based on these results.","subitem_description_type":"Other"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The American Astronomical Society","subitem_publisher_language":"ja"}]},"item_10002_relation_14":{"attribute_name":"item_10002_relation_14","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1086/175793","subitem_relation_type_select":"DOI"}}]},"item_10002_source_id_11":{"attribute_name":"item_10002_source_id_11","attribute_value_mlt":[{"subitem_source_identifier":"AA00553253","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"item_10002_source_id_9","attribute_value_mlt":[{"subitem_source_identifier":"0004637X","subitem_source_identifier_type":"ISSN"}]},"item_1709629224652":{"attribute_name":"item_1709629224652","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1709631006745":{"attribute_name":"TD番号","attribute_value_mlt":[{"interim":"TD00001058"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"HIRANO, Akira","creatorNameLang":"ja"},{"creatorName":"フクエ, ジュン","creatorNameLang":"ja-Kana"},{"creatorName":"福江, 純","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"KITAMOTO, Shunji","creatorNameLang":"ja"}]},{"creatorNames":[{"creatorName":"YAMADA, Tatsuya.T","creatorNameLang":"ja"}]},{"creatorNames":[{"creatorName":"MINESHIGE, Shin","creatorNameLang":"ja"}]},{"creatorNames":[{"creatorName":"FUKUE, Jun","creatorNameLang":"ja"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2007-12-17"}],"filename":"Ast_Jou_446_p350.pdf","format":"application/pdf","mimetype":"application/pdf","url":{"url":"https://osaka-kyoiku.repo.nii.ac.jp/record/2064089/files/Ast_Jou_446_p350.pdf"},"version_id":"19bb62af-9494-4bba-8131-a2b45dda308b"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"accretion","subitem_subject_scheme":"Other"},{"subitem_subject":"accretion disks","subitem_subject_scheme":"Other"},{"subitem_subject":"stars: individual (Cygnus X-2)","subitem_subject_scheme":"Other"},{"subitem_subject":"X-rays: stars","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_title":"ACCRETION DISK STRUCTURE AND BRANCH BEHAVIOR OF CYGNUS X-2","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ACCRETION DISK STRUCTURE AND BRANCH BEHAVIOR OF CYGNUS X-2","subitem_title_language":"en"}]},"item_type_id":"40015","owner":"14","path":["1707194980981"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-12-17"},"publish_date":"2007-12-17","publish_status":"0","recid":"2064089","relation_version_is_last":true,"title":["ACCRETION DISK STRUCTURE AND BRANCH BEHAVIOR OF CYGNUS X-2"],"weko_creator_id":"14","weko_shared_id":-1},"updated":"2025-03-08T14:13:44.271220+00:00"}
