It is found that a pair of persistent quasi-periodic oscillations (twin QPOs) is excited at the resonant radius, where the ratio of Keplerian frequency to epicyclic frequency is close to 2:1. The power spectrum density (PSD) shows that the lower peak frequency corresponds to the Keplerian frequency, while the upper peak frequency corresponds to the sum of Keplerian frequency and epicyclic frequency. The results provide the first direct evidence for the excitation of resonant disk oscillation in MHD accretion flows. It is also found that the emergent spectra from radio to gamma-ray of the MHD accretion flows fluctuates in the wide range of frequency and does not always vary coherently.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0064306027","subitem_description_type":"Other"}]},"item_5_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-SP-08-014E","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"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-113X","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11984031","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構宇宙科学研究本部"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (ISAS)(JAXA)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"加藤, 成晃"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kato, Yoshiaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-16"}],"displaytype":"detail","filename":"64306027.pdf","filesize":[{"value":"2.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"64306027.pdf","url":"https://jaxa.repo.nii.ac.jp/record/5266/files/64306027.pdf"},"version_id":"8b78f27c-a60d-46ae-bd4d-279f51c8c5fe"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"accretion, accretion disks - magnetohydrodynamics : MHD - quasi-periodic oscillations - radiation : radiative transfer","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":"Quasi-periodic osicllations and variable emissions In magnetohydrodynamic accretion flows","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Quasi-periodic osicllations and variable emissions In magnetohydrodynamic accretion flows","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["959","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"5266","relation_version_is_last":true,"title":["Quasi-periodic osicllations and variable emissions In magnetohydrodynamic accretion flows"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T08:19:21.403795+00:00"}
