Here we report on the results of the observations of two spectacular comets. One is the analysis of photometry of C-2 emission images in the coma of comet Hyakutake (C/1996 B2). By comparing the production rates of C-2 radicals with C2H2 molecules, we conclude that the most C-2 radicals were originated from C2H2, while some of them might be produced from other parents. The second item is the analysis of the morphology of C-2 emission images in the coma of comet Hale-Bopp(C/1995 O1). By applying a ringmasking technique, we detected asymmetrical distribution of the C-2 molecules. The results of these two comets might suggest that a portion of C-2 radicals were formed by the disintegration of the small organic dust grains, like the so-called CHON particles.", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "SPRINGER", "subitem_publisher_language": "en"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1023/A:1006237210191"}}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "1573-0794", "subitem_source_identifier_type": "EISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "T Sekiguchi", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "J Watanabe", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "H Fukushima", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "T Yamamoto", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "N Yamamoto", "creatorNameLang": "en"}]}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_title": "Observations of C-2 molecules in the coma of comets at Mitaka", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Observations of C-2 molecules in the coma of comets at Mitaka", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "1", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/4437", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-03-30"}, "publish_date": "2023-03-30", "publish_status": "0", "recid": "4437", "relation": {}, "relation_version_is_last": true, "title": ["Observations of C-2 molecules in the coma of comets at Mitaka"], "weko_shared_id": -1}
