cds-question@unistra.frmultiple-starsinfrared-photometryvisible-astronomyphotometryhertzsprung-russell-diagramWe are presenting VRI photometry of 93 wide visual double stars having late B- or A- type primaries, taken from the Annex of Double and Multiple Stars of the HIPPARCOS Input Catalogue. Spectral types have been estimated for most of the primaries and for the majority of the secondaries. 40% of them probably have common origin components, for which we calculated photometric parallaxes and some orbital values estimates.1995A&AS..112..291Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/112/291CatalogResearchIsServedByTAP VizieR generic servicerelated-toI/107 : WDS (Washington Double Star)I/196 : HIC (Hipparcos Input Catalogue)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/112/291https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/112/291http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/112/291https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/112/291https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/112/291http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/112/291GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/A+AS/112/291/table1VRI photometry of A-type double starsrecnoRecord number assigned by the VizieR team.
