The Distribution of Angles Between Outflows and Magnetic Fields in Low-mass Protostellar Cores
Abstract
Most theoretical models of bipolar outflows from young stars assume that the outflows follow the magnetic-field direction. Yet, in the limited number of sources where dust polarization had already been mapped, misalignments of the outflow and magnetic field axes were common. We present results from the TADPOL survey, a key project at CARMA (the Combined Array for Research in Millimeter-wave Astronomy) that aims to roughly triple the number of high-resolution maps of dust polarization toward low-mass, Class 0 cores. The results accumulated thus far suggest that magnetic fields and bipolar outflows in low-mass cores are not tightly aligned, and may indeed be randomly oriented with respect to one another.
