The synchronization of the macro-spins in this model well describes both the intermittent magnetic reversals in the Earth and the quasi-periodic ones in the Sun. If our macro-spin model were actually general, then many of the convection dominant stars must show magnetic reversals. Thus we set our goal: We try to discover the stellar magnetic reversals by monitoring the Solar type and the stars associated with strong magnetic fields. For this purpose, we use 1.3m Araki Telescope of Koyama Astronomical Observatory in Kyoto Sangyo University. We will improve the high-dispersion Echelle Spectropolarimeter \"VESPolA\" of this telescope for better resolution. We have, so far, observed 12 stars of type G, Ap/Fp, and B, with medium-dispersion R=8,000 linearly polarized mode, during the period of about 10 nights in August and October 2013. An efficient observation method using VESPolA and an effective data analysis have been discussed to find out the optimized modification of the VESPolA.","subitem_description_type":"Other"}]},"item_2_description_15":{"attribute_name":"表示順","attribute_value_mlt":[{"subitem_description":"19","subitem_description_type":"Other"}]},"item_2_description_16":{"attribute_name":"アクセション番号","attribute_value_mlt":[{"subitem_description":"KJ00009319499","subitem_description_type":"Other"}]},"item_2_description_2":{"attribute_name":"ページ属性","attribute_value_mlt":[{"subitem_description":"P","subitem_description_type":"Other"}]},"item_2_description_8":{"attribute_name":"記事種別(日)","attribute_value_mlt":[{"subitem_description":"研究活動報告","subitem_description_type":"Other"}]},"item_2_description_9":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_description":"Activity Report","subitem_description_type":"Other"}]},"item_2_source_id_1":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA11879037","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_19":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1348-8465","subitem_source_identifier_type":"PISSN"}]},"item_2_text_6":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"京都産業大学神山天文台"},{"subitem_text_value":"京都産業大学理学研究科"},{"subitem_text_value":"京都産業大学神山天文台"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"中道, 晶香","creatorNameLang":"ja"},{"creatorName":"NAKAMICHI, Akika","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"7710","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"新崎, 貴之","creatorNameLang":"ja"},{"creatorName":"ARASAKI, Takayuki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"7711","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"池田, 優二","creatorNameLang":"ja"},{"creatorName":"IKEDA, Yuji","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"7712","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-01-28"}],"displaytype":"detail","filename":"KJ00009319499.pdf","filesize":[{"value":"458.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00009319499.pdf","url":"https://ksu.repo.nii.ac.jp/record/2975/files/KJ00009319499.pdf"},"version_id":"ded52ff7-1a65-425e-90c3-4f27f4fce186"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"磁極反転","subitem_subject_scheme":"Other"},{"subitem_subject":"同期現象","subitem_subject_scheme":"Other"},{"subitem_subject":"恒星","subitem_subject_scheme":"Other"},{"subitem_subject":"偏光分光観測装置","subitem_subject_scheme":"Other"},{"subitem_subject":"観測","subitem_subject_scheme":"Other"},{"subitem_subject":"magnetic polarity reversal","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"synchronization","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"stars","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"spectropolarimeter","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"observation","subitem_subject_language":"en","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"恒星の磁極反転","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"恒星の磁極反転","subitem_title_language":"ja"},{"subitem_title":"Magnetic Polarity Reversal of Stars","subitem_title_language":"en"}]},"item_type_id":"2","owner":"3","path":["229"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2018-01-28"},"publish_date":"2018-01-28","publish_status":"0","recid":"2975","relation_version_is_last":true,"title":["恒星の磁極反転"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-09-04T07:23:11.559012+00:00"}
