We combine polarization data from with rotation measure (RM) observations towards a massive star- forming region, Monoceros molecular cloud, study its impact of an expanding H ii region on morphology field. derive analytical solution for field, assumed evolve initially uniform configuration following expansion ionized gas formation shell swept-up ISM. From RM we estimate mean value line-of-sight component about 3 μG (towards observer) Nebula, electron density cm −3 . surrounds is clearly observed intensity map at 353 GHz, signal significantly different local background when considered as whole. constrain plane-of-the-sky orientation Rosette’s parent cloud mostly aligned large-scale along plane. are compared model, which predicts properties spherical given This comparison leads upper limit ◦ angle between line sight complex, intrinsic fraction 4%. direction reproduce values detected if strength range 6.5–9 μG. present model able distribution across nebula, well shell, directly applied other similar objects.
