cds-question@unistra.frmolecular-cloudsradio-astronomyspectroscopyWe present a study of cyanoacetylene (HC_3_N) and cyanodiacetylene (HC_5_N) in Orion KL, using observations from two line surveys performed with the IRAM 30-m telescope and the HIFI instrument onboard the Herschel telescope. The frequency ranges covered are 80-280GHz and 480-1906GHz. This study (divided by families of molecules) is part of a global analysis of the physical conditions of Orion KL and the molecular abundances in the different components of this cloud. We modeled the observed lines of HC_3_N, HC_5_N, their isotopologues (including DC_3_N), and vibrational modes using a non-local thermodynamic equilibrium (non-LTE) radiative transfer code. In addition, to investigate the chemical origin of HC_3_N and DC_3_N in Orion KL, we used a time-dependent chemical model.2013A&A...559A..51Ehttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/559/A51CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJS/156/127 : 350{mu}m molecular line survey of Orion KL (Comito+, 2005)J/A+A/532/A32 : HCOOCH_3_ map of Orion-KL (Favre+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/559/A51https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/559/A51http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/559/A51https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/559/A51https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/559/A51http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/559/A51GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalRadiodefaultJ/A+A/559/A51/tablea1Observed lines of HC_3_N and its isotopologues (ground- and vibrational states)recnoRecord number assigned by the VizieR team.
