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"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-30"},"publish_date":"2023-03-30","publish_status":"0","recid":"4437","relation_version_is_last":true,"title":["Observations of C-2 molecules in the coma of comets at Mitaka"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-03-31T01:53:41.995540+00:00"}
