cds-question@unistra.frglobular-star-clustersspectroscopic-binary-starsradial-velocityWe carried our a radial velocity survey for spectroscopic binaries in the low-density globular cluster NGC 5053. Our sample contains a total of 77 cluster member giant and subgiant stars with visual magnitudes of 14.5-18.6. Of These 77 stars, 66 stars have on average of 3-4 measurements with a total of 236 velocities. A typical velocity error per measurement is 13km/s. The stars in our sample are spatially distributed from the cluster center out to 10arcmin in radius (4.5 core radii). Among theses 66 stars with multiple velocity measurements, we discovered 6 spectroscopic binary candidates.1996AJ....112.1489Yhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/112/1489CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/112/1489https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/112/1489http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/112/1489https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/112/1489https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/112/1489http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/112/1489GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/112/1489/table2a (Relative radial velocities of stars in NGC 5053 (individual data))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/112/1489/table2a?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/112/1489/table2a?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/112/1489/table2a?GETtext/xml+votable180.050000true199.2357037917.758304910.005555555555555556Cone search capability for table J/AJ/112/1489/table2b (Relative radial velocities of stars in NGC 5053 (average data))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/112/1489/table2b?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/112/1489/table2b?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/112/1489/table2b?GETtext/xml+votable180.050000true199.2357037917.758304910.0055555555555555566/27984 27986https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/112/1489?format=asciiOpticaldefaultJ/AJ/112/1489/table2aRelative radial velocities of stars in NGC 5053 (individual data)recnoRecord number assigned by the VizieR team.
