From the magnetic field and ion flux data obtained by the fluxgate magnetometer and the low-energy particle experiments–ion mass analyzer onboard Arase, we find 55 events of the low-energy O^+ flux enhancement accompanied with magnetic field dipolarization in the periods of April 1–October 31, 2017 and July 1, 2018–January 31, 2019. The low-energy O^+ flux enhancements (a) start a few minutes after the dipolarization onset, (b) have energy-dispersed signatures with decreasing energy from a few keV down to ∼10 eV, (c) are observed in both storm and non-storm periods, (d) have a field-aligned distribution (α ∼ 0° in the southern hemisphere and α ∼ 180° in the northern hemisphere), (e) are accompanied by the low-energy H^+ flux enhancements that have lower energies than O^+ by a factor of 3–10, and (f) increase the O^+ density and the O^+/H^+ density ratio by ∼10 times and 4–5 times, respectively. We perform a numerical simulation to trace ion trajectories forward in time from the Arase positions. It is revealed that both H^+ and O^+ ions drift eastward and reach the dawn-to-morning sector without being lost in the ionosphere, if the pitch angle scattering effect is considered near the equatorial plane. This result suggests that these low-energy field-aligned ions can contribute to formation of the warm plasma cloak.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_9_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Wiley","subitem_publisher_language":"en"}]},"item_9_relation_43":{"attribute_name":"関連情報","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1029/2021JA029168","subitem_relation_type_select":"DOI"}}]},"item_9_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2021 American Geophysical Union","subitem_rights_language":"en"}]},"item_9_source_id_7":{"attribute_name":"収録物識別子","attribute_value_mlt":[{"subitem_source_identifier":"2169-9402","subitem_source_identifier_type":"EISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Nosé, M.","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Matsuoka, A.","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Miyoshi, Y.","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Asamura, K.","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Hori, T.","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Teramoto, M.","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Shinohara, I.","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Hirahara, M.","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2022-02-08"}],"displaytype":"detail","filename":"JGR_Space_Physics_2021_Nose.pdf","filesize":[{"value":"14.2 MB"}],"format":"application/pdf","url":{"objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/2002047/files/JGR_Space_Physics_2021_Nose.pdf"},"version_id":"2d5afb9e-e4a1-48e6-94b0-4d1831ec6fd5"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Field-Aligned Low-Energy O^+ Flux Enhancements in the Inner Magnetosphere Observed by Arase","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Field-Aligned Low-Energy O^+ Flux Enhancements in the Inner Magnetosphere Observed by Arase","subitem_title_language":"en"}]},"item_type_id":"40001","owner":"17","path":["881"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2022-02-08"},"publish_date":"2022-02-08","publish_status":"0","recid":"2002047","relation_version_is_last":true,"title":["Field-Aligned Low-Energy O^+ Flux Enhancements in the Inner Magnetosphere Observed by Arase"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-01-16T05:07:12.175666+00:00"}
