cds-question@unistra.frmultiple-starsinfrared-photometryorbitsstellar-distancestellar-radiiWe compile a sample of 341 binary and multiple star systems with the aim of searching for and characterizing Kuiper belt-like debris discs. The sample is assembled by combining several smaller samples studied in previously published work with targets from two unpublished Herschel surveys. We find that 38 systems show excess emission at 70 or 100{mu}m suggestive of a debris disc. While nine of the discs appear to be unstable to perturbations from their host binary based on a simple analysis of their inferred radii, we argue that the evidence for genuine instability is not strong, primarily because of uncertainty in the true disc radii, uncertainty in the boundaries of the unstable regions, and orbital projection effects. The binary separation distributions of the disc-bearing and disc-free systems are different at a confidence level of 99.4 per cent, indicating that binary separation strongly influences the presence of detectable levels of debris. No discs are detected for separations between ~25 and 135au; this is likely a result of binaries whose separations are comparable with typical disc radii clearing out their primordial circumstellar or circumbinary material via dynamical perturbations. The disc detection rate is 19^+5^_-3_ per cent for binaries wider than 135au, similar to the published results for single stars. Only 8^+2^_-1_ per cent of systems with separations below 25au host a detectable disc, which may suggest that planetesimal formation is inhibited in binaries closer than a few tens of au, similar to the conclusions of studies of known planet-hosting binaries.2019MNRAS.488.3588Yhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/488/3588CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/488/3588https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/488/3588http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/488/3588https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/488/3588https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/488/3588http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/488/3588GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/488/3588/table2 (Photometry in the MIPS 70um, PACS 70um, and PACS 100um bands for all systems in our sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/488/3588/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/488/3588/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/488/3588/table2?GETtext/xml+votable180.050000true1.420916145.81208530.0055555555555555566/137 155 188 311 338 404 493 535 684 689 691 765 798 845 902 940 1704 1888 2051 2317 2340 2476 2520 2597 2690 2737 2747 3006 3403 4158 4181 4184 4250 4316 4356 4670 4693 4915 4924 4942 5009 5154 5207 5377 5498 5514 5534 5670 5731 5762-5763 5802 6066 6106 6147 6154 6273 6339-6340 6726 7205 7221 7238 7264 7273 7390 7595 7665 7772 7803 7950 8466 8687 8690 8788 8790 8843 8995 9032 9048 9072 9096 9247 9442 9629 9642 9696 9759 9801 9808 9857 10027 10096 10164 10225 10313 10481 10568 10741 10783 11034 11075 11109 11142 11276 11290 11403 11500 11620 11636 11671 11732 11910 12012 12031 12232 12330 12390 12465 12467 12592 12679 12698 12798 12890 13110 13440 13947 13960 13966 14512 14515 14522 14908 15165 15170 15174 15311 15356 15562 15906 15940 16105 16502 16543 16678 16689 16692 16792 16827 17017 17486 17504 17513 17588 17611 17752 17783 17844 17875 17965 18234 18309 18441 18450 19097 19215 19288 19323 19417 19543 19670 19766 19912 20071 20145 20278 20286 20365 20631 20701 20758 20835 20896 20940 21060 21136 21175 21386 21568 21726 21765 21790 22100 22300 22302 22325 22511 22708 22939 23201 23403 23431 23826 24303 24713 25015 25120 25192 25199 25297 25444 25766 26024 26174 26379 26462 26478 26521 26676 26679 26753 26924 27088 27268 27731 27822 27884 27973 27980 28180 29784 30014 30167 30550 30662 31073 31393 31425 31433 31742 31751 31830 31849 32229 32496 32516 32549 32617 32619 32743 32930 33116 33211 33287 33320 33340 33442 33498 33552 33689 33716 33849 33966 34217 34785 34889 34896 35079 35149 35191 35347 35351 35440 35872 35948 36274 36446 36526 36614 36621 36664 36711 36742 37111 37408 38117 38238 38558 38929 39440-39441 39499-39500 40131 40515 40660 40679 40823 41272 41678 41763 41972 43498 43540 43850-43851 43989 44284 44557 44833 44891 45249 45272 45564 45746 45927 46247 46320 46572 46640 46908 46939 47101 47107 47205 47287 47352 47589 47742 47777 47904 48037 48254 48552 48589 48613 48749 48923 489851.9864425968556103e-21 2.837779945223663e-21https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/488/3588?format=asciiInfrareddefaultJ/MNRAS/488/3588/table1Information on the orbits of the binaries and multiple systems in our samplerecnoRecord number assigned by the VizieR team.
