cds-question@unistra.fryoung-stellar-objectsinterstellar-mediumradio-astronomyradio-spectroscopyWe performed high-angular-resolution observations toward L1157-B1 with the IRAM NOEMA interferometer of the DCN (2-1) and H^13^CN (2-1) lines to compute the deuterated fraction, D_frac_(HCN), and compare it with previously reported D_frac_ of other molecular species. Our aim is to observationally investigate the role of the different chemical processes at work that lead to formation of the DCN and compare it with HDCO, the two deuterated molecules imaged with an interferometer, and test the predictions of the chemical models for their formation.2017A&A...604A..20Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/604/A20CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/604/A20https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/604/A20http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/604/A20https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/604/A20https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/604/A20http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/604/A20GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/604/A20/list (List of data cubes)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/604/A20/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/604/A20/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/604/A20/list?GETtext/xml+votable180.050000true309.7924368.019520.0055555555555555566/15965https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/604/A20?format=asciiRadiodefaultJ/A+A/604/A20/listList of data cubesNxNumber of pixels along X-axismeta.numberintrecnoRecord number assigned by the VizieR team.
