cds-question@unistra.frmultiple-starsCircumstellar dust discs have been observed around many nearby stars. However, many stars are part of binary or multiple stellar systems. A natural question arises regarding the presence and properties of such discs in systems with more than one star. To address this, we consider a sample of 449 systems (spectral types A-M) observed with the Herschel Space Observatory as part of the DEBRIS (Disc Emission via a Bias-free Reconnaissance in the Infrared/Submillimetre) programme. We have examined the stellar multiplicity of this sample by gathering information from the literature and performing an adaptive optics imaging survey at Lick Observatory. Five new companions were revealed with our programme. In total, we identify 188 (42 per cent) binary or multiple star systems. The multiplicity of the sample is examined with regards to the detection of circumstellar discs for stars of spectral types AFGK. In general, discs are less commonly detected around binaries than single stars, though the disc frequency is comparable among A stars regardless of multiplicity. However, this sample reveals the period distribution of disc-bearing binaries is consistent with that of non-disc binaries and with comparison field samples. We find that the properties of discs in binary systems are not statistically different from those around single stars. Although the frequency of disc-bearing FGK binaries may be lower than in single star systems, the processes behind disc formation and the characteristics of these discs are comparable among both populations.2015MNRAS.449.3160Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/449/3160CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/wds : The Washington Visual Double Star Catalog (Mason+ 2001-2014)J/MNRAS/403/1089 : SUNS and DEBRIS surveys target selection (Phillips+, 2010)J/AJ/143/135 : Ages of A-K type stars in DEBRIS survey (Vican, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/449/3160https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/449/3160http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/449/3160https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/449/3160https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/449/3160http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/449/3160GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/449/3160/table1 (DEBRIS sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/449/3160/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/449/3160/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/449/3160/table1?GETtext/xml+votable180.050000true24.7557386-17.95071860.005555555555555556Cone search capability for table J/MNRAS/449/3160/table4 (IRCAL companion measurements)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/449/3160/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/449/3160/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/449/3160/table4?GETtext/xml+votable180.050000true24.7560539-17.95056810.0055555555555555566/4 22 137 183 527 546 684 689 993 2014 2317 2340 2472 2476 2591 2690 2724 2737 2747 3932 4158 4250 4316 4438 4444 4569 4693 4854 4867 5000 5009 5074 5154 5207 5304 5311 5373 5377 5420 5498 5514 5522 5534 5590 5631 5670 5726 5762 5802 5836 5853 6066 6082 6154 6308 6339-6340 6552 6672 6726 6766 6926 6941 7103 7205 7221 7238 7264 7267 7390 7595 7665 7763 7772 7950 8023 8094 8109 8145 8466 8476 8591 8687 8690 8788 8790 8843 8985 8995 9048 9072 9125 9128 9339 9403 9442 9471 9476 9629 9662 9696 9801 9835 10027 10096 10149 10225 10313 10375 10457 10695 10735 10741 10783 10812 10899 10923 11109 11142 11150 11193 11276 11290 11403 11405 11620 11633 11636 11671 11732 11806 11834 12232 12340 12390 12592 12679 12798 12890 13440 13688 14515 14522 14906 14993 15144 15170 15174 15179 15227 15311 15346 15356 16041 16105 16289 16391 16412 16502 16518 16543 16678 16689 16692 16758 16827 17017 17028 17171 17194 17219 17348 17425 17486 17576 17588 17752 17783 17965 18139 18440-18441 18450 18496 18553 18761 18804 18821 19323 19329 19466 19585 19766 19912 20071 20100 20145 20278 20328 20459 20701 20896 21060 21136 21177 21289 21568 21726 21788 22014 22277 22289 22300 22309 22325 22511 22645 22708 22818 22822 23056 23190 23201 23230 23369 23910 24028 24713 24729 24777 24793 24924 25015 25056 25192 25199 25444 25766 25820 25966 25973 26024 26174 26216 26279 26327 26379 26462 26521 26538 26560 26583 26699 26972 26975 27088 27201 27268 27374 27392 27459 27462 27730-27731 27735 27762 27794 27884 27954 27973 27980 28122 28180 28316 28343 28352 28605 28664 30176 30543 31087 31393 31412 31425 31433 31448 31478 31849 32229 32288 32335 32496 32619 32757 32848 32930 33116 33211 33340 33351 33425 33442 33552 33716-33717 33813 33818 33849 33964-33965 33976 34054 34181 34217 34345 34446 34448 34479 34817 34896 34905 35064 35079 35149 35351 35474 35753 35802 35948 36081 36145 36248 36288 36351 36365 36446 36483 36526 36614 36664 36697 36711 36735 36762 36804 37020 37290 37408 38219 38238 38489 38667 38929 39149 39441 39499-39500 40242 40505 40679 40692 40716 40811 40932 41272 42022 42054 42253 42652 43318 43539-43540 43580 43676 43723 43809 43850-43851 43989 44226 44284 44482 44557 44681 44833 44891 44921 44937 45032 45247 45272 45334 45374 45412 45472 45485 45535 45564 45589 45668 45746 45927 45941 45982-45983 45992 46113 46131 46244 46247 46281 46320 46566 46632 46640 46718 46776 46908 46939 46956 46982 47061 47101 47107 47112 47137 47347 47352 47414 47589 47598 47758 47777 47910 48037 48254 48291 48334 48355 48589 48652 48705 48906 48923 48985https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/449/3160?format=asciidefaultJ/MNRAS/449/3160/table1DEBRIS sampleSimbadNameSimbad column added by the CDSmeta.idcharnullableUNSidUNS identifiermeta.idcharrecnoRecord number assigned by the VizieR team.
