cds-question@unistra.frx-ray-binary-starsgamma-ray-astronomyspectroscopyThe INTEGRAL hard X-ray observatory has revealed an emerging population of highly obscured X-ray binary systems through multi-wavelength observations. Previous studies have shown that many of these sources are high-mass X-ray binaries hosting neutron stars orbiting around luminous and evolved companion stars. To better understand this newly-discovered population, we have selected a sample of sources for which an accurate localisation is available to identify the stellar counterpart and reveal the nature of the companion star and of the binary system.2008A&A...484..783Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/484/783CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/484/783https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/484/783http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/484/783https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/484/783https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/484/783http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/484/783GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapGamma-rayOpticaldefaultJ/A+A/484/783/table8Spectroscopy resultsrecnoRecord number assigned by the VizieR team.
