cds-question@unistra.frmagellanic-cloudsx-ray-binary-starsphotometryThe spectral distributions of Be/X-ray binaries in the Large Magellanic Cloud and Galaxy have been shown to differ significantly from the distribution of isolated Be stars in the Galaxy. Population synthesis models can explain this difference in spectral distributions through substantial angular momentum loss from the binary system. In this work, we explore the spectral distribution of Be/X-ray binaries in the Small Magellanic Cloud (SMC) using high signal-to-noise ratio spectroscopy of a sample of 37 optical counterparts to known X-ray pulsars. Our results show that the spectral distribution of Be/X-ray binaries in the SMC is consistent with that of the Galaxy, despite the lower metallicity environment of the SMC. This may indicate that, although the metallicity of the SMC is conducive to the formation of a large number of high-mass X-ray binaries, the spectral distribution of these systems is likely to be most strongly influenced by angular momentum losses during binary evolution, which are not particularly dependent on the local metallicity.2008MNRAS.388.1198Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/388/1198CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/388/1198https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/388/1198http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/388/1198https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/388/1198https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/388/1198http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/388/1198GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/388/1198/table24 (Sample and properties of SMC Be/X-ray binary systems with well-defined optical counterparts (tables 2 and 4 of the paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/388/1198/table24?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/388/1198/table24?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/388/1198/table24?GETtext/xml+votable180.050000true11.3965-73.31750.0055555555555555566/33293-33295 33298 33304 33306 33317 33328https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/388/1198?format=asciiOpticaldefaultJ/MNRAS/388/1198/table24Sample and properties of SMC Be/X-ray binary systems with well-defined optical counterparts (tables 2 and 4 of the paper)recnoRecord number assigned by the VizieR team.
