cds-question@unistra.frearly-type-starsradial-velocityinfrared-photometryproper-motionswolf-rayet-starso-starsThe central parsec around the supermassive black hole in the Galactic center (GC) hosts more than 100 young and massive stars. Outside the central cusp (R~1") the majority of these O and Wolf-Rayet (W-R) stars reside in a main clockwise system, plus a second, less prominent disk or streamer system at large angles with respect to the main system. Here we present the results from new observations of the GC with the AO-assisted near-infrared imager NACO and the integral field spectrograph SINFONI on the ESO/VLT. These include the detection of 27 new reliably measured W-R/O stars in the central 12" and improved measurements of 63 previously detected stars, with proper motion uncertainties reduced by a factor of 4 compared to our earlier work. Based on the sample of 90 well measured W-R/O stars, we develop a detailed statistical analysis of their orbital properties and orientations. We show that half of the W-R/O stars are compatible with being members of a clockwise rotating system.2009ApJ...697.1741Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/697/1741CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/499/483 : NIR observations of sources in galactic center (Buchholz+,J/ApJ/681/1254 : Radial velocities of stars in the Galactic Center (Zhu+ 2008)J/ApJ/643/1011 : Early-type stars in the center of the Galaxy (Paumard+ 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/697/1741https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/697/1741http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/697/1741https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/697/1741https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/697/1741http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/697/1741GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/697/1741/table1 (K magnitudes, positions, proper motions and radial velocities of the 90 W-R/O stars used in our analysis)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/697/1741/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/697/1741/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/697/1741/table1?GETtext/xml+votable180.050000true266.41658972-29.007886110.0055555555555555566/288307.952274030004205e-20 1.0188844282367877e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/697/1741?format=asciiOpticalInfrareddefaultJ/ApJ/697/1741/table1K magnitudes, positions, proper motions and radial velocities of the 90 W-R/O stars used in our analysisrecnoRecord number assigned by the VizieR team.
