cds-question@unistra.frastrometryap-starspeculiar-variable-starsmultiple-starsinterferometryWe present the results of speckle interferometry of a sample of 117 chemically peculiar stars with global magnetic fields. The observations were made in December 2009 at the BTA with a spatial resolution of about 0.02 arcseconds in the visual spectral region. Twenty-nine stars were resolved into individual components, 14 of them for the first time (HD965, HD5797, HD8855, HD10783, HD16605, HD21699, HD35502, HD51418, HD64486, HD79158, HD103498, HD108651, HD213918, HD293764). In twelve cases a companion turned out to be 2-4 magnitudes fainter than the main component - a magnetic star. Young hot Bp stars HD35502 and HD213918 are exceptions, since their companions are fainter by about 1 magnitude. In all cases, the linear distance from a star to its companion at the epoch of observations in the picture plane exceeded 10^9^km. Eighty-eight magnetic CP stars revealed no secondary components within our study. Thus, the fraction of speckle interferometric binaries in our sample amounts to 25%.2012AstBu..67...44Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/AstBu/67.44CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/other/AstBu/69.269 : Paper II. 2010-2012 observations (Rastegaev+, 2014)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/AstBu/67.44https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/AstBu/67.44http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/AstBu/67.44https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/AstBu/67.44https://vizier.iucaa.in/viz-bin/votable?-source=J/other/AstBu/67.44http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/AstBu/67.44GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/AstBu/67.44/table1 (Positional parameters for 27 binary systems with magnetic Ap/Bp primary components)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/AstBu/67.44/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/other/AstBu/67.44/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/AstBu/67.44/table1?GETtext/xml+votable180.050000true3.5169292-0.03336390.0055555555555555566/1768 2395 2817 3030 4206 5501 5805 6759 7705 8094 13559 14272 14718 15408 15631 17888 18086 18273 22727 22815 22831 22837 22884 23641 24562 28142https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/AstBu/67.44?format=asciiOpticaldefaultJ/other/AstBu/67.44/table1Positional parameters for 27 binary systems with magnetic Ap/Bp primary componentse_rho[1/22] Error of rhomasstat.errorintrecnoRecord number assigned by the VizieR team.
