HC5N is generally though to be formed by growth of carbon chain of HC3N. I carried out observations of the normal species and the five 13C isotopologues of HC5N in order to confirm its main formation pathway. I found that main formation mechanism of HC5N is ion-molecule reactions involving a nitrogen atom. I also conducted quantitative evaluation of contributions of each pathway using the 14N\/15N and 12C\/13C ratios, and concluded that about 70% of HC5N molecules have been formed by the ion-molecule reactions involving a nitrogen atom. <\/p>\n<p>[Speaker2]<br \/>\nMisaki Ando , M1, SOKENDAI, Mitaka(supervisor: Daisuke Iono)<br \/>\n[Title]<br \/>\nThe condition of molecular gas in starburst galaxy<\/p>\n<p>[Speaker3]<br \/>\nYoshida Masaki , M1, SOKENDAI, Mitaka(supervisor: Suematsu Yoshinori)<br \/>\n[Title]<br \/>\nEstimating a reconnection rate based on an observation of inflow and flare ribbon expansion <\/p>\n","protected":false},"excerpt":{"rendered":"<p>[Speaker1] TANIGUCHI Kotomi , D1, SOKENDAI, Mitaka(supervisor: SAITO Masao) [Title] Formation Mechanisms of HC [&hellip;]<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6,5],"tags":[],"class_list":["post-478","post","type-post","status-publish","format-standard","hentry","category-6","category-5"],"_links":{"self":[{"href":"https:\/\/guas-astronomy.jp\/weblog\/index.php?rest_route=\/wp\/v2\/posts\/478","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/guas-astronomy.jp\/weblog\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/guas-astronomy.jp\/weblog\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/guas-astronomy.jp\/weblog\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/guas-astronomy.jp\/weblog\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=478"}],"version-history":[{"count":0,"href":"https:\/\/guas-astronomy.jp\/weblog\/index.php?rest_route=\/wp\/v2\/posts\/478\/revisions"}],"wp:attachment":[{"href":"https:\/\/guas-astronomy.jp\/weblog\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=478"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/guas-astronomy.jp\/weblog\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=478"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/guas-astronomy.jp\/weblog\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=478"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
