The star, V1647 Ori, is the same star that underwent an accretion-powered outburst in 2003-2005; during this eruption we recorded, for the first time, a sustained X-ray outburst from a rapidly accreting YSO. The X-ray activity is suspected to be driven by a star-disk magnetic dynamo, accompanied by rapid mass accretion. However, observations that might support or refute this hypothesis have been limited in quantity and quality. We triggered a ToO observation of V1647 Ori with Suzaku for 40 ksec on 2008 October 8 using Director's Discretionary Time. During the observation, V1647 Ori showed a gradual flux decrease by a factor of 5 and then displayed an abrupt flux increase by an order of magnitude. The spectrum clearly displays emission from Helium-like iron, which is a signature of hot plasma (kT approximately 5 keV). Such X-ray properties were also seen in an XMM-Newton observation during the first outburst, but it has rarely been observed for other YSOs. Hence, the new outburst started in 2008 is likely driven by a mechanism similar to that of the first outburst. The Suzaku/XIS spectrum of V1647 Ori also shows a remarkable fluorescent iron K line with an equivalent width of approximately 600 eV. Such a large equivalent width indicates that a part of the incident X-ray emission that irradiates the circumstellar material is hidden from our line of sight.","subitem_description_type":"Other"}]},"item_5_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Meeting sponsors: The University of Tokyo, The Institute of Physical and Chemical Research, The Japan Society for the Promotion of Science","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0064574070","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-09-008E","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_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"CRESST and X-ray Astrophysics Laboratory NASA/GSFC"},{"subitem_text_language":"en","subitem_text_value":"Observatoire astronomique de Strasbourg, Universite de Strasbourg"},{"subitem_text_language":"en","subitem_text_value":"Rochester Institute of Technology"},{"subitem_text_language":"en","subitem_text_value":"Vanderbilt University"},{"subitem_text_language":"en","subitem_text_value":"Vanderbilt University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Hamaguchi, Kenji","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Grosso, Nicolas","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kastner, Joel H.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Weintraub, David A.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Richmond, Michael","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":"64574070.pdf","filesize":[{"value":"193.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"64574070.pdf","url":"https://jaxa.repo.nii.ac.jp/record/5002/files/64574070.pdf"},"version_id":"cdb6d4d7-167e-42d9-9bc9-6aa4876ceba2"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"stars: formation - stars: individual (V1647 Ori) - stars: pre-main-sequence - X-rays: stars","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":"Suzaku Observation of a New X-ray Outburst from the Accreting Young Star Illuminating McNeil's Nebula","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Suzaku Observation of a New X-ray Outburst from the Accreting Young Star Illuminating McNeil's Nebula","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["948","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"5002","relation_version_is_last":true,"title":["Suzaku Observation of a New X-ray Outburst from the Accreting Young Star Illuminating McNeil's Nebula"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T08:26:26.451540+00:00"}
