cds-question@unistra.frsurveysmultiple-starsspectroscopic-binary-starso-starsapparent-magnitudestellar-associationsWe present the results of an all-sky survey made with the Fine Guidance Sensor on the Hubble Space Telescope to search for angularly resolved binary systems among massive stars. The sample of 224 stars is comprised mainly of Galactic O- and B-type stars and luminous blue variables, plus a few luminous stars in the Large Magellanic Cloud. The FGS TRANS mode observations are sensitive to the detection of companions with an angular separation between 0.01'' and 1.0'' and brighter than {delta}m=5. The FGS observations resolved 52 binary and 6 triple star systems and detected partially resolved binaries in 7 additional targets (43 of these are new detections). These numbers yield a companion detection frequency of 29% for the FGS survey. We also gathered literature results on the numbers of close spectroscopic binaries and wider astrometric binaries among the sample, and we present estimates of the frequency of multiple systems and the companion frequency for subsets of stars residing in clusters and associations, field stars, and runaway stars. These results confirm the high multiplicity fraction, especially among massive stars in clusters and associations. We show that the period distribution is approximately flat in increments of logP. We identify a number of systems of potential interest for long-term orbital determinations, and we note the importance of some of these companions for the interpretation of the radial velocities and light curves of close binaries that have third companions.2015AJ....149...26Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/149/26CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/wds : The Washington Visual Double Star Catalog (Mason+ 2001-2014)III/274 : Galactic O-Star Spectroscopic Survey (Sota+, 2014)V/116 : Galactic O star catalog (Maiz-apellaniz+, 2004)III/84 : Galactic O Stars (Cruz-Gonzalez+ 1974)II/82 : Galactic O-type Stars (Garmany+ 1982)III/84 : Galactic O Stars (Cruz-Gonzalez+ 1974)J/MNRAS/424/1925 : Spectrocopic Binarity of O and B type stars (Chini+, 2012)J/A+A/518/A1 : Galactic massive stars with AstraLux (Maiz Apellaniz, 2010)J/AJ/137/3358 : Speckle interferometry of massive stars (Mason+, 2009)J/MNRAS/400/518 : Velocity & proper motion of OB associations (Melnik+, 2009)J/A+A/366/508 : S Dor variables (van Genderen+, 2001)http://ssg.iaa.es/en/content/galactic-o-star-catalog/ : Galactic O-Star Cataloghttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/149/26https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/149/26http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/149/26https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/149/26https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/149/26http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/149/26GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/149/26/table1 (Stellar parameters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/149/26/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/149/26/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/149/26/table1?GETtext/xml+votable180.050000true1.51412563.67966670.0055555555555555565/3673 9927 6/1196 1287 1293 1302-1303 1558 1790 2409 2806 3066 3214 3231 3283 3300-3301 3307-3308 3384 3430 3644 5506 6891 12943 13255 13281 13557 13999 14008 14179 14630 14636 14641 14645-14646 14653-14654 14670 14690 14712 14745 14824 15369 15478 15625 15672 15683 15745 21439 21504 21510 21518 21531 21635 21638 21647 21655-21656 21804 22022 22033 22038 22088 22122-22123 22126 22164 22208 22211 22216 22240 22243 22249 22253 22258 22517 22854 22885 23637 23717 23774 23780 23832 23851 23962 23982 23984 23995-23996 23998 24179 24328 24496 28687 28804 28819 28833 28890-28891 28915 29036 29089 29095 29116 29463 29513 29537 29600 33098 33100 37245 37334 37339 37349 37362-37363 37366 37750 37758 37833 37850-37851 37861 37863 37869-37870 37872 37880 37882 37907 37923 37926 37930-37931 37934 37938 37948 38016 38020 38536 39222 39238 39248-39249 39252-39254 39264 39281 39369 39374 39384 39386 39410 39733 39771 39774-39775 39788 39793 39796 39799 39803-39804 39873 39876 39907 39916 39930-39931 39971 40618-40619 41103 41610 41655 41673 41685-41686 41994 42213 42283 42303 42383 42387 42416 42470 42764 43040 430623.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/149/26?format=asciidefaultJ/AJ/149/26/table1Stellar parametersSimbadNameSimbad column added by the CDSmeta.idcharnullablerecnoRecord number assigned by the VizieR team.
