Magnetic fields in accretion disks play a dominant part during the star formation process but have hitherto been observationally poorly constrained. Field strengths have been inferred on T Tauri stars and possibly in the innermost part of their accretion disks, but the strength and morphology of the field in the bulk of a disk have not been observed.(More)
We present λ 1.3mm CARMA observations of dust polarization toward 30 star-forming cores and 8 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(More)
