| Abstract | We present the first 850 mu m polarization observations in the most active star-forming site of the Rosette Molecular Cloud (d similar to 1.6 kpc) in the wall of the Rosette Nebula, imaged with the SCUBA-2/POL-2 instruments of the James Clerk Maxwell telescope, as part of the B-Fields In Star-forming Region Observations 2 (BISTRO-2) survey. From the POL-2 data we find that the polarization fraction decreases with the 850 mu m continuum intensity with alpha = 0.49 +/- 0.08 in the p proportional to I (-alpha ) relation, which suggests that some fraction of the dust grains remain aligned at high densities. The north of our 850 mu m image reveals a "gemstone ring" morphology, which is a similar to 1 pc diameter ring-like structure with extended emission in the "head" to the southwest. We hypothesize that it might have been blown by feedback in its interior, while the B-field is parallel to its circumference in most places. In the south of our SCUBA-2 field the clumps are apparently connected with filaments that follow infrared dark clouds. Here, the POL-2 magnetic field orientations appear bimodal with respect to the large-scale Planck field. The mass of our effective mapped area is similar to 174 M (circle dot), which we calculate from 850 mu m flux densities. We compare our results with masses from large-scale emission-subtracted Herschel 250 mu m data and find agreement within 30%. We estimate the plane-of-sky B-field strength in one typical subregion using the Davis-Chandrasekhar-Fermi technique and find 80 +/- 30 mu G toward a clump and its outskirts. The estimated mass-to-flux ratio of lambda = 2.3 +/- 1.0 suggests that the B-field is not sufficiently strong to prevent gravitational collapse in this subregion. |
