cds-question@unistra.frinterstellar-mediummolecular-cloudsradio-spectroscopyNitrogen bearing species, such as NH_3_, N_2_H^+^, and their deuterated isotopolo- gues show enhanced abundances in CO-depleted gas, and thus are perfect tracers of dense and cold gas in star-forming regions. The Taurus molecular cloud contains the long L1495 filament providing an excellent opportunity to study the process of star formation in filamentary environments. We study the kinematics of the dense gas of starless and protostellar cores traced by the N_2_D^+^(2-1), N_2_H^+^(1-0), DCO^+^(2-1), and H^13^CO^+^(1-0) transitions along the L1495 filament and the kinematic links between the cores and surrounding molecular cloud. We measured velocity dispersions, local and total velocity gradients, and estimate the specific angular momenta of 13 dense cores in the four transitions using on-the-fly observations with the IRAM 30-m antenna. To study a possible connection to the filament gas, we used the C^18^O(1-0) observations.2018A&A...617A..27Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/617/A27CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/554/A55 : C^18^O(1-0) and N_2_H^+^(1-0) in L1495/B213 (Hacar+, 2013)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/617/A27https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/617/A27http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/617/A27https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/617/A27https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/617/A27http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/617/A27GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/617/A27/list (List of fits maps)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/617/A27/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/617/A27/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/617/A27/list?GETtext/xml+votable180.050000true64.4791227.935660.005555555555555556Associated datahttps://cdsarc.cds.unistra.fr/assocdata/?obs_collection=J/A+A/617/A276/1074-1075 1082 1168https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/617/A27?format=asciiMillimeterdefaultJ/A+A/617/A27/listList of fits mapsSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
