cds-question@unistra.frexoplanetsmultiple-starsstellar-distanceeffective-temperaturevisible-astronomyinfrared-astronomyWe investigate whether the tentative correlation between planets and debris discs which has been previously identified can be confirmed at high significance. We compile a sample of 201 stars with known planets and existing far-infrared observations. The sample is larger than those studied previously since we include targets from an unpublished Herschel survey of planet hosts. We use spectral energy distribution modelling to characterize Kuiper belt analogue debris discs within the sample, then compare the properties of the discs against a control sample of 294 stars without known planets. Survival analysis suggests that there is a significant (p~0.002) difference between the disc fractional luminosity distributions of the two samples. However, this is largely a result of the fact that the control sample contains a higher proportion of close binaries and of later-type stars; both of these factors are known to reduce disc detection rates. Considering only Sun-like stars without close binary companions in each sample greatly reduces the significance of the difference (p~0.3). We also find no evidence for a difference in the disc fractional luminosities of stars hosting planets more or less massive than Saturn (p~0.9). Finally, we find that the planet hosts have cooler discs than the control stars, but this is likely a detection bias, since the warmest discs in the control sample are also the faintest, and would thus be undetectable around the more distant planet hosts. Considering only discs in each sample that could have been detected around a typical planet host, we find p~0.07 for the temperatures.2020MNRAS.495.1943Yhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/495/1943CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/403/1089 : SUNS and DEBRIS surveys target selection (Phillips+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/495/1943https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/495/1943http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/495/1943https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/495/1943https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/495/1943http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/495/1943GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/495/1943/table3 (Photometry in the MIPS 70{mu}m, PACS 70{mu}m, and PACS 100{mu}m bands for all systems studied in this paper)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/495/1943/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/495/1943/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/495/1943/table3?GETtext/xml+votable180.050000true1.5798972-49.07518640.0055555555555555566/4 22 137 431 527 546 679 684 748 993 1597 2014 2110 2254 2317 2416 2472 2476 2724 2737 3932 3979 4104 4136 4158 4250 4316 4429 4438 4444 4528 4854 4867 5000 5009 5074 5154 5207 5304 5309 5377 5420 5488 5498 5514 5522 5534 5590 5670 5718 5726 5802 5836 5853 6066 6308 6552 6672 6726 6760 6766 6791 6831 6926 6941 7103 7238 7240 7264 7390 7595 7665 7746 7763 7772 7950 8023 8094 8109 8145 8357 8466 8476 8591 8788 8790 8843 8985 8995 9128 9339 9403 9442 9459 9471 9476 9483 9629 9662 9696 9801 9835 9843 10027 10149 10313 10375 10457 10735 10812 10899 11087 11142 11150 11276 11290 11403 11405 11620 11633 11636 11671 11699 11732 11806 11834 11910 12146 12232 12340 12390 12465 12644 12679 12798 12890 12899 12983 13440 13688 14278 14412 14434 14515 14522 14525 14548 14993 15170 15174 15227 15311 15346 15356 16041 16105 16391 16412 16502 16518 16627 16652 16678 16689 16692 16758 16827 17017 17028 17171 17219 17266 17341 17348 17425 17496 17576 17588 17730 17752 17965 18139 18440-18441 18496 18553 18614 18641 18666 18761 18821 19323 19466 19585 19766 19904 19912 20100 20145 20278 20328 20459 20593 20701 20896 21003 21060 21076 21136 21177 21568 21726 21838 21906 21956 22014 22036 22277 22289 22300 22309 22325 22590 22645 22654 22708 22818 22878 23030 23056 23190 23230 23363 23369 23681 23910 24019 24028 24178 24227 24713 24729 24777 24831 24924 25192 25444 25766 25820 25939 25966 26183 26216 26242 26327 26379 26462 26538 26560 26575 26583 26699 26706 26972 26975 26997 27018 27088 27201 27268 27374 27392 27459 27462 27616 27730-27731 27750 27762 27954 27973 27975 27980 28122 28130 28180 28343 28400 28548 28605 28664 28763 29291 29513 29541 30015 30176 30505 30526 30771 31087 31216 31393 31425 31433 31478 31494 32335 32491 32509 32561 32619 32757 32848 32930 33116 33243 33258 33340 33425 33442 33456 33552 33630 33717 33813 33818 33849 33923 33964-33965 34069 34181 34345 34446 34448 34479 34817 34896 34905 35064 35079 35351 35362 35442 35753 35802 35928 35948 35954 35968 36078 36145 36174 36248 36288 36365 36446 36483 36664 36697 36735 36762 37018 37020 37408 37461 37573 37954-37955 38219 38238 38461 38545 38728 38744 38807 39257 39280 39441 39499-39500 39646 39926 40242 40442 40505 40513 40679 40692 40716 40811 40932 40985 41272 41446 41591 41607 41724 41941 42022 42044 42054 42101 42248 42253 42290 42314 42318 42333 42510 42652 42760 43012 43203 43228 43318 43336 43580 43639 43677 43723 43813 43818 43851 43911 43989 44226 44243 44284 44398 44482 44557 44681 44891 44921 44937 45032 45143 45168 45272 45334 45364 45412 45472 45485 45535 45564 45668 45865 45941 45982 45992 46113 46131 46244 46247 46297 46306 46320 46566 46632 46640 46718 46776 46800 46956 46967 46982 47101 47107 47137 47347 47352 47414 47550 47589 47598 47740 47758 47910 48105 48254 48291 48334 48355 48545 48652 48705 48906 48923 489851.9864425968556103e-21 2.837779945223663e-21https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/495/1943?format=asciiOpticalInfrareddefaultJ/MNRAS/495/1943/table1List of stars in our planet host samplerecnoRecord number assigned by the VizieR team.
