Magnetic fields and outflows in the large Bok globule CB 54

ABSTRACT We have observed the large Bok globule CB 54 in 850-$\mu$m polarized light using POL-2 polarimeter on James Clerk Maxwell Telescope (JCMT). find that magnetic field periphery of shows a significant, ordered deviation from mean-field direction centre. This appears to correspond with extended but relatively weak 12CO outflow emanating Class 0 sources at centre globule. Energetics analysis suggests if is reshaping globule’s periphery, then we can place an upper limit $\lt 27\, \mu$G strength periphery. Comparison archival Planck and CARMA measurements consistent over several orders magnitude size scale, oriented parallel density structure region projection. thus hypothesize while non-thermal motions may be sub-Alfvénic, subdominant gravity wide range scales. Our results suggest even able significantly reshape fields star-forming regions scales >0.1 pc.
