cds-question@unistra.frx-ray-binary-starsmagellanic-cloudsphotometryvisible-astronomyWe present an analysis of the long-term optical/IR behavior of 111 high-mass X-ray binaries (HMXBs) in the Small Magellanic Cloud, based on data from the OGLE collaboration. Most systems exhibit variability on a range of timescales. This variability regulates the mass transfer to the compact object, while the compact object can, in turn, affect the donor star's behavior. To better understand this complex interaction and the resulting X-ray properties in these systems, we define a new taxonomy for the observed super-orbital variability. This taxonomy connects to the color changes, orbital periods, and X-ray behavior of the sources. In most cases, these properties can be explained by differences between the flux of the disk around the Be star and the flux from the star itself. We also refine and present new potential orbital periods and sub-orbital variability in the sources.2025A&A...694A..43Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/694/A43CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/586/A81 : High-mass X-ray binaries in the SMC (Haberl+, 2016)J/MNRAS/466/1019 : Bright HMXBs in THINGS galaxies (Sazonov+, 2017)J/A+A/665/A31 : Neutron-star kicks in HMXBs with Gaia EDR3 (Fortin+, 2022)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/694/A43https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/694/A43http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/694/A43https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/694/A43https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/694/A43http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/694/A43GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/694/A43/table2 (Identifying information of HMXBs in our sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/694/A43/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/694/A43/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/694/A43/table2?GETtext/xml+votable180.050000true19.2716667-73.44333330.0055555555555555566/32959 33293-33295 33297-33299 33304-33306 33317 33328https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/694/A43?format=asciiX-rayOpticaldefaultJ/A+A/694/A43/table2Identifying information of HMXBs in our samplerecnoRecord number assigned by the VizieR team.
