cds-question@unistra.frsurveysmolecular-cloudsradio-astronomymillimeter-astronomysubmillimeter-astronomyinterstellar-mediumWe have carried out an H^13^CO^+^(J=1-0 at 86.75433GHz) core survey in a large area of 1deg^2^, covering most of the dense region in the Orion B molecular cloud, using the Nobeyama 45m radio telescope with the 25-BEam Array Receiver System. We cataloged 151 dense cores using the clumpfind method. The cores have mean radius, velocity width, and mass of 0.10+/-0.02pc, 0.53+/-0.15km/s, and 8.1+/-6.4M_{sun}_, respectively, which are very similar to those in the Orion A cloud. We examined the spatial relation between our H^13^CO^+^ cores and the 850um cores observed by Johnstone and colleagues in 2001 (Cat. J/ApJ/559/307) and 2006 (Cat. J/ApJ/639/259), and found that there are two types of spatial relationships: H^13^CO^+^ cores with and without the 850um cores. Since the mean density of the 850um cores is higher than that of the H^13^CO^+^ cores, we can interpret the H^13^CO^+^ cores with 850um cores as being more centrally concentrated and hence more evolved, compared with those without.2009ApJ...691.1560Ihttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/691/1560CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/665/1194 : Dense cores in the Orion A cloud survey (Ikeda+, 2007)J/ApJ/639/259 : Sub-mm clumps in Orion B South molecular cloud (Johnstone+,J/ApJ/559/307 : Sub-mm mapping in Orion B molecular cloud (Johnstone+, 2001)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/691/1560https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/691/1560http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/691/1560https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/691/1560https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/691/1560http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/691/1560GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/691/1560/table1 (Physical properties of the H^13^CO^+^ cores in the Orion B cloud)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/691/1560/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/691/1560/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/691/1560/table1?GETtext/xml+votable180.050000true85.29583-1.779250.0055555555555555566/22854 22855 22861 22873 22876https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/691/1560?format=asciiRadiodefaultJ/ApJ/691/1560/table1Physical properties of the H^13^CO^+^ cores in the Orion B cloudrecnoRecord number assigned by the VizieR team.
