The magnetic field in the NGC 2024 FIR 5 dense core [PDF]
, 2010 We used the Submillimeter Array (SMA) to observe the thermal polarized dust emission from the protostellar source NGC 2024 FIR 5. The polarized emission outlines a partial hourglass morphology for the plane-of-sky component of the core magnetic field ...
