cds-question@unistra.fremission-line-starspre-main-sequence-starspolarimetryinfrared-astronomyWe present the complete sample of protoplanetary disks from the Gemini- Large Imaging with the Gemini Planet Imager Herbig/T Tauri Survey, which observed bright Herbig Ae/Be stars and T Tauri stars in near-infrared polarized light to search for signatures of disk evolution and ongoing planet formation. The 44 targets were chosen based on their near- and mid-infrared colors, with roughly equal numbers of transitional, pre-transitional, and full disks. Our approach explicitly did not favor well-known, 'famous' disks or those observed by the Atacama Large Millimeter/submillimeter Array, resulting in a less-biased sample suitable to probe the major stages of disk evolution during planet formation. Our optimized data reduction allowed polarized flux as low as 0.002% of the stellar light to be detected, and we report polarized scattered light around 80% of our targets. We detected point-like companions for 47% of the targets, including three brown dwarfs (two confirmed, one new), and a new super-Jupiter-mass candidate around V1295 Aql. We searched for correlations between the polarized flux and system parameters, finding a few clear trends: the presence of a companion drastically reduces the polarized flux levels, far-IR excess correlates with polarized flux for nonbinary systems, and systems hosting disks with ring structures have stellar masses <3M_{sun}_. Our sample also included four hot, dusty "FS CMa" systems, and we detected large-scale (>100au) scattered light around each, signs of extreme youth for these enigmatic systems. Science-ready images are publicly available through multiple distribution channels using a new FITS file standard that has been jointly developed with members of the Very Large Telescope Spectro-polarimetric High-contrast Exoplanet Research team.2022AJ....164..109Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/164/109CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/164/109https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/164/109http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/164/109https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/164/109https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/164/109http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/164/109GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/164/109/table5 (Polarization flux and point-source detection upper limits)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/164/109/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/164/109/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/164/109/table5?GETtext/xml+votable180.050000true253.6868714-36.88849080.005555555555555556Cone search capability for table J/AJ/164/109/list (List of polarized light images)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/164/109/list?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/164/109/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/164/109/list?GETtext/xml+votable180.050000true253.68692-36.888560.005555555555555556Associated datahttps://cdsarc.cds.unistra.fr/assocdata/?obs_collection=J/AJ/164/1096/21316 21438 21646 22023 22854-22855 23003 23644 23704 23738 23798 25113 28762 28921 29207 30188 30251 31259 32065 36956 37169 37186 37353 37362 37364 37886 37916 37978 38002 41472 41526 42387 42392 42429 42595 42611 42644 42736 42931 42972 44356 44362 47828https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/164/109?format=asciiInfrareddefaultJ/AJ/164/109/table5Polarization flux and point-source detection upper limitsSimbadNameSimbad column added by the CDSmeta.idcharnullablerecnoRecord number assigned by the VizieR team.
