We investigate the origin of short X-ray flares which are occasionally observed in early stages of afterglows of gamma-ray bursts (GRBs).    Methods. We observed two Swift events, GRB 071112C and GRB 080506, before the start of X-ray flares in the optical and near-infrared (NIR) bands with the 1.5-m Kanata telescope. In conjunction with published X-ray and optical data, we analyzed densely sampled light curves of the early afterglows and spectral energy distributions (SEDs) in the NIR-X-ray ranges.    Results. We found that the SEDs had a break between the optical and X-ray bands in the normal decay phases of both GRBs regardless of the model for the correction of the interstellar extinction in host galaxies of GRBs. In the X-ray flares, X-ray flux increased by 3 and 15 times in the case of GRB 071112C and 080506, respectively, and the X-ray spectra became harder than those in the normal decay phases. No significant variation in the optical-NIR range was detected together with the X-ray flares.    Conclusions. These results suggest that the X-ray flares were associated with either late internal shocks or external shocks from two-component jets.","subitem_description_language":"en"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"EDP Sciences S A"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_source_identifier":"0004-6361","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"AA00553195","subitem_source_identifier_type":"NCID"}]},"item_1617187024783":{"attribute_name":"Page Start","attribute_value_mlt":[{"subitem_start_page":"A56-1"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"2010-09","bibliographicIssueDateType":"Issued"},"bibliographicPageEnd":"A56-9","bibliographicPageStart":"A56-1","bibliographicVolumeNumber":"519","bibliographic_titles":[{"bibliographic_title":"Astronomy & Astrophysics"},{"bibliographic_title":"Astronomy & Astrophysics"}]}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_1617353299429":{"attribute_name":"Relation","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1051/0004-6361/201014272","subitem_relation_type_select":"DOI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://dx.doi.org/10.1051/0004-6361/201014272","subitem_relation_type_select":"DOI"}}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2023-03-18"}],"displaytype":"simple","filename":"AstronAstrophys_519_A56.pdf","filesize":[{"value":"384.6 KB"}],"mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://hiroshima.repo.nii.ac.jp/record/2006324/files/AstronAstrophys_519_A56.pdf"},"version_id":"9d1806c5-16b1-429e-a7db-20e75574ef8e"}]},"item_1732771732025":{"attribute_name":"旧ID","attribute_value":"30783"},"item_title":"Infrared/optical-X-ray simultaneous observations of X-ray flares in GRB 071112C and GRB 080506","item_type_id":"40003","owner":"41","path":["1730444907710"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-18"},"publish_date":"2023-03-18","publish_status":"0","recid":"2006324","relation_version_is_last":true,"title":["Infrared/optical-X-ray simultaneous observations of X-ray flares in GRB 071112C and GRB 080506"],"weko_creator_id":"41","weko_shared_id":-1},"updated":"2025-02-21T07:19:49.882346+00:00"}
