We found a “helix” pattern of jet from one the water fountains and obtained its annual parallax distance. In another source, we found high velocity components of carbon-monoxide emission and an extremely low 12CO/13CO intensity ratio. These results suggest that the parental stars of the water fountains should be intermediate-mass (2—8 solar masses) stars and the jets should play a major role to shape planetary nebulae.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_8_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学","subitem_publisher_language":"ja"},{"subitem_publisher":"Kagoshima University","subitem_publisher_language":"en"}]},"item_8_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"440","subitem_subject_scheme":"NDC"}]},"item_8_text_41":{"attribute_name":"科研費番号 ","attribute_value_mlt":[{"subitem_text_value":"20540234"}]},"item_8_version_type_14":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"今井, 裕","creatorNameLang":"ja"},{"creatorName":"IMAI, Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"22653","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000070374155","nameIdentifierScheme":"NRID","nameIdentifierURI":" "}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-27"}],"displaytype":"detail","filename":"20540234seika.pdf","filesize":[{"value":"255.3 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"20540234seika.pdf","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/4639/files/20540234seika.pdf"},"version_id":"770d3367-6c3a-422c-871c-406f31e29427"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"電波天文学","subitem_subject_language":"ja","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"老星ジェットの探査と超精密解像観測","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"老星ジェットの探査と超精密解像観測","subitem_title_language":"ja"},{"subitem_title":"Surveys and high resolution imaging of jets from evolved stars","subitem_title_language":"en"}]},"item_type_id":"8","owner":"18","path":["79"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2015-01-06"},"publish_date":"2015-01-06","publish_status":"0","recid":"4639","relation_version_is_last":true,"title":["老星ジェットの探査と超精密解像観測"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-05-23T02:18:05.676614+00:00"}
