cds-question@unistra.frx-ray-binary-starsaccretionradial-velocityline-intensitiesWe present the identification of optical counterparts to 23 GBS X-ray sources. All sources are classified as accreting binaries according to the emission-line characteristics inferred from medium-resolution spectroscopy. To distinguish accreting binaries from chromospherically active objects, we develop criteria based on H{alpha} and HeI {lambda}{lambda}5786, 6678 emission-line properties available in the literature. The spectroscopic properties and photometric variability of each object is discussed and a classification is given where possible. At least 12 of the 23 systems show an accretion-dominated optical spectrum and another 6 show stellar absorption features in addition to emission lines indicating that they are probably accreting binaries in quiescence or in a low accretion rate state. Two sources are confirmed to be eclipsing: CX207 and CX794. CX207 is likely a magnetic cataclysmic variable (CV), while CX794 is a nova-like CV in the period gap. Finally, the large broadening (2100km/s FWHM) of the H{alpha} emission lines in CX446 and CX1004 suggests that they are also high-inclination or even eclipsing systems. Whether the compact object is a white dwarf in an eclipsing CV, a neutron star or a black hole in a high-inclination low-mass X-ray binary remains to be established.2014MNRAS.440..365Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/440/365CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/761/162 : Tycho-2 stars in Galactic Bulge Survey (Hynes+, 2012)J/ApJS/194/18 : The Galactic Bulge Survey: X-ray observations (Jonker+, 2011)J/ApJS/210/18 : X-ray survey of the Galactic Bulge (CXOGBS) (Jonker+, 2014)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/440/365https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/440/365http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/440/365https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/440/365https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/440/365http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/440/365GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/440/365/table1 (Source position and log of the VIMOS and Mosaic-II observations)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/440/365/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/440/365/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/440/365/table1?GETtext/xml+votable180.050000true264.94577-27.30245390.0055555555555555565/7213 6/28818 28837 28848-28850 28866 28872 28896 28898https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/440/365?format=asciiOpticaldefaultJ/MNRAS/440/365/table1Source position and log of the VIMOS and Mosaic-II observationsObsIDs?
