Plasma-flow observation shows a characteristic pattern of the flow around the comet as an obstacle. The pickup shells of water-group ions and protons of cometary origin were clearly identified in the phase-space distribution. It is interesting to note that the shell is incompletely filled (by 50-70% of the filling factor). Field-line draping around the comet was observed within 2×10^5km of the Halley's nucleus, where magnetic-field directions are derived from the symmetry axes of the ion-pickup shells. Other ions, such as CO^+ (and/or N_2^+) and CH^+ (and/or C^+), were also identified from energy per charge spectrum near the closest approach. Flow turbulence was observed as short-term (period of ≲2min) fluctuations of the anisotropy direction in the outer cometosheath (2-4.5×10^5km from the nucleus), while the flow was found to be laminar near the closest approach (1.5-2×10^5km from the nucleus). An abrupt change of the plasma parameter was detected around 4.5×10^5km away from the nucleus, representing the bow-shock crossing. The mass-loading effect was observed at a distance of up to ∿1×10^6km. Spatial distribution of density of water-group ions (identified up to 4×10^6km from the nucleus) is also presented.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0166814000","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":"電波研究所平磯支所"},{"subitem_text_value":"京都大学地球物理教室"},{"subitem_text_value":"東海大学航空宇宙学科"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"向井, 利典"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"三宅, 亘"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"寺沢, 敏夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"北山, 正信"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"平尾, 邦雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MUKAI, Toshifumi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MIYAKE, Wataru","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TERASAWA, Toshio","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KITAYAMA, Masanobu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HIRAO, Kunio","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":"SA0166814.pdf","filesize":[{"value":"915.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0166814.pdf","url":"https://jaxa.repo.nii.ac.jp/record/32985/files/SA0166814.pdf"},"version_id":"80652efb-0bbe-4be8-af33-2d348ad8a0a3"}]},"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」で観測されたハレー彗星と太陽風の相互作用","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"「すいせい」で観測されたハレー彗星と太陽風の相互作用"}]},"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":"32985","relation_version_is_last":true,"title":["「すいせい」で観測されたハレー彗星と太陽風の相互作用"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:18:51.182945+00:00"}
