The major findings obtained from these observations are as follows : 1) Strong short-term variation of the Ly α intensities of comet Halley; Such a rapid variation was quite unexpected in the knowledge of the past Ly α observations of comet. In relation to this variation, an accurate determination of the rotation period of this comet was attempted (52.9 hours). 2) The first measurement of the Ly α intensities from within a thick hydrogen cloud of comet. While the intensity distribution as a function of the distance from the nucleus approximately follows that predicted by the Haser model, it is also compatible with the jet repetition model. 3) Existence of a fine structure in the above photometry data, which possibly represents local enhancements of the atomic hydrogen density. 4) Brightness variation within one rotational period was pursued, producing an outburst occurrence diagram. The rapid variation of the Ly α intensities as observed suggests that in an outburst event there must be involved a small amount of hydrogen-containing molecules whose photodissociation lifetimes are quite short. 5) The observed images are brighter (overally twice) than those expected from the nominal model by IACC/WG.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0166813000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙科学研究所"}]},"item_9_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0285-9920","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00354485","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学理学部地球物理研究施設"},{"subitem_text_value":"東海大学工学部"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"金田, 栄祐"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"平尾, 邦雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"足原, 修"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"清水, 幹夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"伊藤, 富造"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"小田, 稔"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KANEDA, E.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HIRAO, K.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"ASHIHARA, O.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SHIMIZU, M.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"ITOH, T.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"ODA, M.","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":"2020-01-24"}],"displaytype":"detail","filename":"SA0166813.pdf","filesize":[{"value":"970.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0166813.pdf","url":"https://jaxa.repo.nii.ac.jp/record/32984/files/SA0166813.pdf"},"version_id":"e2ecc63b-9edb-45e0-891c-a81a03cc60cf"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"「すいせい」によるハレー彗星紫外 (L_yα) 観測","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"「すいせい」によるハレー彗星紫外 (L_yα) 観測"}]},"item_type_id":"9","owner":"1","path":["1890","1912"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"32984","relation_version_is_last":true,"title":["「すいせい」によるハレー彗星紫外 (L_yα) 観測"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:18:52.995380+00:00"}
