The effects of general relativity make it the maximum at 4α, decrease it inward and eventually make it zero at 3a, where a is the Schwarzschild radius. This implies that a low-frequency wave excited in the inner disk is trapped and cannot propagate outward much beyond the region of radius 4α. Characteristics of this trapped oscillation are examined under some approximations. For typical values of parameters, the oscillation period of 100d, which is a typical observed period of time variations of QSOs and Seyfert galaxies, is realized when the mass of the black hole is 10^9-10^10 M_sun.","subitem_description_type":"Other"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Astronomical Society of Japan","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/10.1093/pasj/62.3.635","subitem_relation_type_select":"DOI"}}]},"item_10002_source_id_11":{"attribute_name":"item_10002_source_id_11","attribute_value_mlt":[{"subitem_source_identifier":"AA00795296","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"item_10002_source_id_9","attribute_value_mlt":[{"subitem_source_identifier":"00046264","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":"TD00000679"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"KATO, Shoji","creatorNameLang":"ja"},{"creatorName":"フクエ, ジュン","creatorNameLang":"ja-Kana"},{"creatorName":"福江, 純","creatorNameLang":"en"}]},{"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":"2007-11-05"}],"filename":"Pub_Ast_Soc_32_p377.pdf","format":"application/pdf","mimetype":"application/pdf","url":{"url":"https://osaka-kyoiku.repo.nii.ac.jp/record/2063933/files/Pub_Ast_Soc_32_p377.pdf"},"version_id":"316d4f05-df64-4130-9460-dbb3bb42d962"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Accretion disks","subitem_subject_scheme":"Other"},{"subitem_subject":"Black holes","subitem_subject_scheme":"Other"},{"subitem_subject":"QSOs","subitem_subject_scheme":"Other"},{"subitem_subject":"Schwarzschild radius","subitem_subject_scheme":"Other"},{"subitem_subject":"Trapped oscillations","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_title":"Trapped Radial Oscillations of Gaseous Disks around a Black Hole","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Trapped Radial Oscillations of Gaseous Disks around a Black Hole","subitem_title_language":"en"}]},"item_type_id":"40015","owner":"14","path":["1707194980981"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-11-05"},"publish_date":"2007-11-05","publish_status":"0","recid":"2063933","relation_version_is_last":true,"title":["Trapped Radial Oscillations of Gaseous Disks around a Black Hole"],"weko_creator_id":"14","weko_shared_id":-1},"updated":"2025-03-08T14:05:26.289006+00:00"}
