cds-question@unistra.frpolarimetrysurveysinfrared-astronomyThe Herschel Space telescope carried out an unprecedented survey of nearby stars for debris discs. The dust present in these debris discs scatters and polarizes stellar light in the visible part of the spectrum. We explore what can be learned with aperture polarimetry and detailed radiative transfer modelling about stellar systems with debris discs. We present a polarimetric survey, with measurements from the literature, of candidate stars observed by DEBRIS and DUNES Herschel surveys. We perform a statistical analysis of the polarimetric data with the detection of far-infrared excess by Herschel and Spitzer with a sample of 223 stars. Monte Carlo simulations were performed to determine the effects of various model parameters on the polarization level and find the mass required for detection with current instruments. Eighteen stars were detected with a polarization 0.01=<P~<0.1 per cent and >=3{sigma}_P_, but only two of them have a debris disc. No statistically significant difference is found between the different groups of stars, with, without, and unknown status for far-infrared excess, and presence of polarization. The simulations show that the integrated polarization is rather small, usually <0.01 per cent for typical masses detected by their far-infrared excess for hot and most warm discs. Masses observed in cold discs can produce polarization levels above 0.01 per cent since there is usually more dust in them than in closer discs. We list five factors which can explain the observed low-polarization detection rate. Observations with high-precision polarimeters should lead to additional constraints on models of unresolved debris discs.2019MNRAS.483.3510Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/483/3510CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/483/3510https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/483/3510http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/483/3510https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/483/3510https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/483/3510http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/483/3510GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/483/3510/table1 (All stars observed at OMM and from the Leroy compilation with a polarization P>=3{sigma}_P_)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/483/3510/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/483/3510/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/483/3510/table1?GETtext/xml+votable180.050000true199.212714217.01717810.005555555555555556Cone search capability for table J/MNRAS/483/3510/tablea1 (Polarization data for all the stars observed at OMM and from the Leroy compilation with a polarization P<3{sigma}_P_)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/483/3510/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/483/3510/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/483/3510/tablea1?GETtext/xml+votable180.050000true165.83414535.96988220.0055555555555555566/137 684 689 993 2014 2317 2340 2476 2591 2690 3932 4158 4250 4316 4438 4444 4854 5009 5074 5154 5207 5304 5311 5373 5377 5420 5498 5514 5522 5534 5631 5670 5726 5762 5802 5836 5853 6066 6082 6154 6308 6339-6340 6552 6672 6726 6766 6926 7205 7221 7238 7264 7267 7390 7595 8466 8476 8591 8687 8690 8790 8843 9048 9072 9125 9128 9339 9442 9662 9696 9801 9835 10096 10313 10375 10457 10695 10741 10783 10899 10923 11109 11142 11150 11193 11276 11290 11403 11405 11636 11732 11834 12390 12798 12890 13440 14522 15144 15179 15356 16105 16289 16412 16518 16689 17219 17486 17588 17752 17783 17965 18139 18441 18804 19323 19329 19585 19766 20125 21060 21177 21289 21788 22277 22289 22300 22309 22511 22822 23190 23230 23369 23575 23910 24028 24793 24924 25015 25056 25199 25444 25973 26024 26174 26462 26583 26975 27088 27201 27268 27374 27392 27459 27794 27884 27954 27973 27980 28122 28180 28316 28343 28352 28605 28664 30543 31087 31448 31478 31849 32229 32335 32496 32619 33211 33351 33716-33717 33849 33976 34446 34817 35064 35474 35802 35948 36081 36145 36351 36446 36711 36762 37290 38238 38667 38929 40679 41272 42253 43809 43850 45032 45485 45535 46131 46281 46320 46908 46925 46956 46982 47101 48355 48589 48652https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/483/3510?format=asciiInfrareddefaultJ/MNRAS/483/3510/table1All stars observed at OMM and from the Leroy compilation with a polarization P>=3{sigma}_P_ObsSource of the data (G6)meta.bibchare_P/dError on P/d1e-05pc**-1stat.errorfloatFIR[YN?] Presence of a disc according to far-infrared excess (Gaspar et al. 2013ApJ...768...25G, Cat.
