The L1157-B1 astrochemical laboratory: testing the origin of DCN. Busquet, G., Fontani, F., Viti, S., Codella, C., Lefloch, B., Benedettini, M., Ceccarellli, C. <Astron. Astrophys. 604, A20 (2017)> =2017A&A...604A..20B (SIMBAD/NED BibCode)
ADC_Keywords: YSOs ; Interstellar medium ; Radio lines ; Spectra, millimetric/submm Keywords: ISM: jets and outflows - ISM: molecules - ISM: abundances - stars: formation Abstract: We performed high-angular-resolution observations toward L1157-B1 with the IRAM NOEMA interferometer of the DCN (2-1) and H13CN (2-1) lines to compute the deuterated fraction, Dfrac(HCN), and compare it with previously reported Dfrac 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. Description: IRAM NOEMA observations of DCN(2-1) and H13CN(2-1) toward the brightest bow-shock B1 of the L1157 molecular outflow. All data cubes are provided in fits format smoothed to a velocity resolution of 0.5km/s.
