Constraints are provided by high-resolution R = 45,000, high-S/N spectra of the three quasars HE0141-3932, HE0429-4091, and HE2243-6031, which we have obtained from the ESO archive of VLT UVES. Results are as follows.(1) The single-cloud weak Mg II absorption in the three z similar to 1.7 systems is produced by clouds with ionization parameters of -3.8 < log U less than or similar to -2.0 and sizes of 1-100 pc. (2) In addition to the low-ionization phase Mg II clouds, all systems need an additional one to three high-ionization phase C IV clouds within 100 km s(-1) of the Mg II component. The ionization parameters of the C IV clouds range from -1.9 < log U < -1.0, with sizes of tens of parsecs to kiloparsecs. (3) Two of the three single-cloud weak Mg II absorbers have near-solar or supersolar metallicities, if we assume a solar abundance pattern. Although such large metallicities have been found for z < 1 weak Mg II absorbers, these are the first high metallicities derived for such systems at higher redshifts. (4) Two of the three weak Mg II systems also need additional low-metallicity, broad Ly alpha absorption lines, offset in velocity from the metal-line absorption, in order to reproduce the full Ly alpha profile. (5) Metallicities in single-cloud weak Mg II systems are more than an order of magnitude larger than those in DLA systems at z similar to 1.7. In fact, there appears to be a gradual decrease in metallicity with increasing N-H (I), from these, the most metal-rich Ly alpha forest clouds, to Lyman limit systems, to sub-DLAs, and finally to the DLAs.","subitem_description_type":"Abstract"}]},"item_6_description_30":{"attribute_name":"資源タイプ（コンテンツの種類）","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_6_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"The Astrophysical Journal. 679:220-238 (2008)","subitem_description_type":"Other"}]},"item_6_link_3":{"attribute_name":"信州大学研究者総覧へのリンク","attribute_value_mlt":[{"subitem_link_text":"Misawa, T","subitem_link_url":"http://soar-rd.shinshu-u.ac.jp/profile/ja.ypchuUkV.html"}]},"item_6_link_67":{"attribute_name":"WoS","attribute_value_mlt":[{"subitem_link_url":"http://gateway.isiknowledge.com/gateway/Gateway.cgi?&GWVersion=2&SrcAuth=ShinshuUniv&SrcApp=ShinshuUniv&DestLinkType=FullRecord&DestApp=WOS&KeyUT=000255818600017"}]},"item_6_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The American Astronomical Society"}]},"item_6_relation_48":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1086/586691"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1086/586691","subitem_relation_type_select":"DOI"}}]},"item_6_source_id_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0004-637X","subitem_source_identifier_type":"ISSN"}]},"item_6_source_id_40":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00553253","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Misawa,  T"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Charlton,  JC"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Narayanan,  A"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2015-09-28"}],"displaytype":"detail","filename":"ApJ_679_220.pdf","filesize":[{"value":"960.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ApJ_679_220.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/15876/files/ApJ_679_220.pdf"},"version_id":"81831f30-ddbf-4039-8f64-7fef5e8292f3"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"galaxies : abundances","subitem_subject_scheme":"Other"},{"subitem_subject":"intergalactic medium","subitem_subject_scheme":"Other"},{"subitem_subject":"quasars : absorption lines","subitem_subject_scheme":"Other"},{"subitem_subject":"quasars : individual (HE 0141-3932, HE 0429-4901, HE 2243-6031)","subitem_subject_scheme":"Other"}]},"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":"Supersolar metallicity in weak MgII absorption systems at z similar to 1.7","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Supersolar metallicity in weak MgII absorption systems at z similar to 1.7","subitem_title_language":"en"}]},"item_type_id":"6","owner":"1","path":["1545"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2010-06-04"},"publish_date":"2010-06-04","publish_status":"0","recid":"15876","relation_version_is_last":true,"title":["Supersolar metallicity in weak MgII absorption systems at z similar to 1.7"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-14T04:01:47.118662+00:00"}
