For solving this problem, it is crucial to probe the dynamics of the outer atmosphere. The milliarcsecond angular resolution achieved by IR long-baseline interferometry provides us with the only way to spatially resolve this key region. We present high spatial and high spectral resolution observations of the best-studied RSGs Betelgeuse and Antares in the 2.3 μm CO lines using ESO’s Very Large Telescope Interferometer (VLTI). We have succeeded in \"velocity-resolved\" aperturesynthesis imaging of the atmosphere of stars for the first time. This allows us to probe not only inhomogeneous structures over the surface of stars but also their kinematics, as routinely done in solar physics. We have detected vigorous upwelling and downdrafting motions of large CO gas clumps (as large as the radius of the stars) at up to 20-30 km s(exp −1) within 1.5 stellar radii. SPICA will provide a unique opportunity to probe the region farther away from the star, helping us to link the inhomogeneous, vigorous atmospheric motions to the physical properties of the circumstellar envelope.","subitem_description_type":"Other"}]},"item_5_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: カラー図版あり","subitem_description_type":"Other"}]},"item_5_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA1730027059","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-17-010E","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(JAXA)"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_22":{"attribute_name":"ISSNONLINE","attribute_value_mlt":[{"subitem_source_identifier":"2433-2232","subitem_source_identifier_type":"ISSN"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"The Max Planck Institute for Radio Astronomy"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"大仲, 圭一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ohnaka, Keiichi","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":"2020-01-15"}],"displaytype":"detail","filename":"AA1730027059.pdf","filesize":[{"value":"271.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA1730027059.pdf","url":"https://jaxa.repo.nii.ac.jp/record/3036/files/AA1730027059.pdf"},"version_id":"bac7af10-83d1-4a34-a68e-5f143fbdf2cb"}]},"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":"Resolving the Mass Loss in Red Supergiants with the Very Large Telescope Interferometer and SPICA","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Resolving the Mass Loss in Red Supergiants with the Very Large Telescope Interferometer and SPICA","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["807","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-05-01"},"publish_date":"2018-05-01","publish_status":"0","recid":"3036","relation_version_is_last":true,"title":["Resolving the Mass Loss in Red Supergiants with the Very Large Telescope Interferometer and SPICA"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T09:11:19.318272+00:00"}
