cds-question@unistra.fryoung-stellar-objectspolarimetrymillimeter-astronomysubmillimeter-astronomyWe present {lambda}1.3mm Combined Array for Research in Millimeter-wave Astronomy observations of dust polarization toward 30 star-forming cores and eight star-forming regions from the TADPOL survey. We show maps of all sources, and compare the ~2.5" resolution TADPOL maps with ~20" resolution polarization maps from single-dish submillimeter telescopes. Here we do not attempt to interpret the detailed B-field morphology of each object. Rather, we use average B-field orientations to derive conclusions in a statistical sense from the ensemble of sources, bearing in mind that these average orientations can be quite uncertain. We discuss three main findings. (1) A subset of the sources have consistent magnetic field (B-field) orientations between large (~20") and small (~2.5") scales. Those same sources also tend to have higher fractional polarizations than the sources with inconsistent large-to-small-scale fields. We interpret this to mean that in at least some cases B-fields play a role in regulating the infall of material all the way down to the ~1000AU scales of protostellar envelopes. (2) Outflows appear to be randomly aligned with B-fields; although, in sources with low polarization fractions there is a hint that outflows are preferentially perpendicular to small-scale B-fields, which suggests that in these sources the fields have been wrapped up by envelope rotation. (3) Finally, even at ~2.5" resolution we see the so-called polarization hole effect, where the fractional polarization drops significantly near the total intensity peak.2014ApJS..213...13Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/213/13CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/226 : Stellar polarization catalogs agglomeration (Heiles, 2000)VII/9 : Lynds' Catalogue of Bright Nebulae (Lynds 1965)J/ApJ/716/893 : Polarisation at 850mu{m} in OMC-2 and OMC-3 (Poidevin+, 2010)J/ApJS/186/406 : 350um polarimetry from CSO (Dotson+, 2010)J/ApJS/185/451 : PMS stars in the Cepheus flare region (Kun+, 2009)J/ApJ/707/103 : Observation of Ser FIRS 1 at 230GHz (Enoch+, 2009)J/ApJS/182/143 : SCUPOL Legacy polarimetry of SCUBA (Matthews+, 2009)J/A+A/494/147 : T Tauri stars in CB 26 molecular outflows (Launhardt+, 2009)J/A+A/490/213 : 1.4 and 3.4mm interferometry of W3 IRS5 (Rodon+, 2008)J/A+A/476/1243 : Millimeter continuum mapping of Cygnus X (Motte+, 2007)J/MNRAS/379/663 : 850um observations of W3 giant molecular cloud (Moore+, 2007)J/A+A/468/1009 : Star formation in Perseus.
