Abstract
AbstractWe present polarimetric observations of the Bok globule CB54 in the far‐infrared via SOFIA/HAWC+ bands D (154 m) and E (214 m). We detect polarization with mean polarization degrees of 5.4 and 5.4 at 154 and 214 m, respectively. The polarization degree decreases toward the inner region of CB54, revealing a “polarization hole”. This finding can be explained by the impact of dichroic absorption counteracting the effect of polarized emission. The same effect allows us to explain the observed wavelength‐dependent orientation of the linear polarization in the dense, central region of CB54. The polarization pattern appears uniform at core scales but un‐ordered at larger scales—similar to what was found in previous studies of this object. The mean polarization angle amounts to = 62.4 44.5° and = 60.0° at 154 and 214 m, respectively.
