These are naturally explained if there is a third star in the system. Multiplicity is also required to explain some comparisons of "cool plus hot binary" IUE and optical spectral energy distribution analysis with measured flux ratios, especially Tycho's two-color photometry of separate components. Out of a sample of 136 cool-plus-hot binary star systems under study, measurements are now indicating several systems considered double (HD 5373, 23089, 26673, 29094, 49126, 71129, 149379, 179002, 187299), and probably a few others (including HD 136415), to have at least three stellar components. Several other cases of suspected triple systems are confirmed. For comparison, there are eight known triples included in the project. In all, about 25% of the systems contain three or more components within a few arcseconds. Estimated separations are provided, which may be of use when not known from interferometry. In general, the triple systems have one post-main-sequence component and two upper main-sequence components, usually revolving around each other. One new triple system, HD 149379, has as its middle component an F giant in the brief first crossing of the Hertzsprung gap.2004AJ....127.2915Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/127/2915CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/119/83 : IUE sample of binaries with hot component (Parsons+, 1998)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/127/2915https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/127/2915http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/127/2915https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/127/2915https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/127/2915http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/127/2915GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/127/2915/table3 (Flux Magnitudes for Multiple and Additional Cool-plus-Hot Systems)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/127/2915/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/127/2915/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/127/2915/table3?GETtext/xml+votable180.050000true12.68171664.247550.0055555555555555566/1448 1618 2685 3372 3462 3723 4143 9469 12517 12529 13238 13414 13777 13961 14359 14613 14866 15444 15810 16952 20797 23562 24235 29878 30363 31904 37207 37760 39344 39972 41757 44720 48104 48856 49101https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/127/2915?format=asciiUVOpticalInfrareddefaultJ/AJ/127/2915/table1Summary of Additional IUE Observations, extension of table 1 of J/ApJS/119/83IUEFind IUE SpectracharrecnoRecord number assigned by the VizieR team.
