cds-question@unistra.frearly-type-starsemission-line-starswolf-rayet-starsradial-velocityinfrared-astronomyspectroscopyThe Galactic centre hosts a crowded, dense nuclear star cluster with a half-light radius of 4pc. Most of the stars in the Galactic centre are cool late-type stars, but there are also >=100 hot early-type stars in the central parsec of the Milky Way. These stars are only 3-8Myr old. Our knowledge of the number and distribution of early-type stars in the Galactic centre is incomplete. Only a few spectroscopic observations have been made beyond a projected distance of 0.5pc of the Galactic centre. The distribution and kinematics of early-type stars are essential to understand the formation and growth of the nuclear star cluster.2015A&A...584A...2Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/584/A2CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/584/A2https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/584/A2http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/584/A2https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/584/A2https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/584/A2http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/584/A2GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/584/A2/table2 (Emission-line and Wolf-Rayet stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/584/A2/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/584/A2/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/584/A2/table2?GETtext/xml+votable180.050000true266.41684-29.00748310.005555555555555556Cone search capability for table J/A+A/584/A2/table3 (Stars with featureless spectra)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/584/A2/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/584/A2/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/584/A2/table3?GETtext/xml+votable180.050000true266.41888-29.00637190.005555555555555556Cone search capability for table J/A+A/584/A2/tableb (List of O/B stars (tables B1-B3))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/584/A2/tableb?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/584/A2/tableb?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/584/A2/tableb?GETtext/xml+votable180.050000true266.41745-29.00765190.0055555555555555566/288307.952274030004205e-20 1.0188844282367877e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/584/A2?format=asciiOpticalInfrareddefaultJ/A+A/584/A2/table2Emission-line and Wolf-Rayet starsS/NSignal-to-noisestat.snrfloatrecnoRecord number assigned by the VizieR team.
