cds-question@unistra.frpolarimetryWe investigate the linear polarization produced by interstellar dust aligned by the magnetic field in the solar neighborhood (d<50pc). We also look for intrinsic effects from circumstellar processes, specifically in terms of polarization variability and wavelength dependence. We aim to detect and map dust clouds which give rise to statistically significant amounts of polarization of the starlight passing through the cloud, and to determine the interstellar magnetic field direction from the position angle of the observed polarization. High-precision broad-band (BVR) polarization observations are made of 361 stars in spectral classes F to G, with detection sensitivity at the level of or better than 10E-5 (0.001%). The sample consists of 125 stars in the magnitude range 6-9 observed at the 2.2m UH88 telescope on Mauna Kea, 205 stars in the magnitude range 3-6 observed at the Japanese (Tohoku) T60 telescope on Haleakala, and 31 stars in the magnitude range 4-7 observed at the 1.27m H127 telescope of the Greenhill Observatory, Tasmania. Identical copies of the Dipol-2 polarimeter are used on these three sites. Statistically significant (>3sigma) polarization is found in 115 stars, and >2sigma detection in 178 stars, out of the total sample of 361 stars. Polarization maps based on these data show filament-like patterns of polarization position angles which are related to both the heliosphere geometry, the kinematics of nearby clouds, and the Interstellar Boundary EXplorer (IBEX) ribbon magnetic field. From long-term multiple observations, a number (18) of stars show evidence of intrinsic variability at the 10E-5 level. This can be attributed to circumstellar effects (e.g., debris disks and chromospheric activity). The star HD 101805 shows a peculiar wavelength dependence, indicating size distribution of scattering particles different from that of a typical interstellar medium. Our high-S/N measurements of nearby stars with very low polarization also provide a useful dataset for calibration purposes.2020A&A...635A..46Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/635/A46CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/635/A46https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/635/A46http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/635/A46https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/635/A46https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/635/A46http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/635/A46GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/635/A46/table6 (Polarization data from the UH88 telescope)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/635/A46/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/635/A46/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/635/A46/table6?GETtext/xml+votable180.050000true1.47791718.2350.005555555555555556Cone search capability for table J/A+A/635/A46/table7 (Polarization data from the T60 telescope)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/635/A46/table7?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/635/A46/table7?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/635/A46/table7?GETtext/xml+votable180.050000true1.56583358.4366670.005555555555555556Cone search capability for table J/A+A/635/A46/table8 (Broad-band (400-800nm) polarimetric data of nearby stars observed at the H127 telescope)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/635/A46/table8?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/635/A46/table8?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/635/A46/table8?GETtext/xml+votable180.050000true66.775-46.94750.0055555555555555566/137 248 313 377 455 464 742 944 1024 1028 1032 1167 1247 1296 1341 1577 1711 1779 2027 2072 2169 2222 2299 2418 2456 2472 2476 2636 2697 2919 2961 3006 3036 3102 3118 3258 3314 3430 3662 3691 3932 3986 4147 4184 4227 4333 4366 4377 4438 4569 4670 4808 4854 4867 5009 5074 5088 5154 5304 5311 5522 5718 5731 5777 5836 5895 6066 6073 6106 6308 6398 6523 6528 6890 6926 6941 6998 7221 7243 7355 7390 7595 7695 8109 8249 8286 8433 8451 8475 8716-8717 8748 8881 8993 9072 9181 9323 9331 9403 9443 9480 9808 9835 9883 10090 10334 10424 10701 10812 10886 11128 11150 11225 11314 11403 11546 11691 11844 12337 12798 12922 12944 13164 13725 13931 14140 14144 14146 14180 14459 14502 14845 15170 15177 15631 15712 15962 16192 16606 16652 16679 16697 16723 16883 16986 17171 17177 17218 17486 17496 17576 17588 17606 17847 17860 17944 18139 18184 18330 18441 18712 19312 19323 19424 19470 19517 19796 19830 19874 19900 19923 20127 20605 20657 20739 20758 20872 21080 21091 21142 21179 21185 21240 21289 21484 21543 21631 21696 21699 21788 21790 21867 22123 22183 22193 22240 22285 22349 22355 22361 22594 22630 22654 22746 22764 22773 22818 22823 22841 22878 23018 23161 23177 23190 23339 23382 23408 23539 23547 23675 23870 23893 23974 24027-24028 24212 24536 24769 24793 24924 24944 25068 25070 25311 25407 25435 25444 25473 25567 25793 25828 25873 25966 26521 26575 26676 26753 27006 27040 27083 27130 27254-27255 27262 27268 27334 27347 27616 27690 27757 27794 27980 28041 28282 29255 29289 29349 29368 29422 29680 29842 29913 29978 30109 30378 30576 30943 30951 31325 31412 31433 31667 31789 32192 32357 32575 32585 33838 33849 34004 34028 34064 34204 34577 34745 35977 35994 36035 36047 36081 36145 36365 36421 36564 36635 36711 36723 36762 36770 36813 37020 37125 37158 37408 37419 37680 37807 38064 38235 38535 38614 39028 39031 39034 39112 39283 39305 39373 39490 39576 39676 39854 39926 40242 40544 40679 40692 40716 40802 40823 40932 42918 42933 43688 44010 44398 44401 44755 44910 45029 47101 48531 48606 48943 491283.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/635/A46?format=asciidefaultJ/A+A/635/A46/table6Polarization data from the UH88 telescopeplxParallaxmaspos.parallax.trigfloatVmagV magnitudemagphot.mag;em.opt.Vfloatl_plx[~] limit flag on plxmeta.code.error;pos.parallaxcharSpTypeSpectral typesrc.spTypecharrecnoRecord number assigned by the VizieR team.
