Scientific paper
We present high spatial resolution (~0.8 arcsec) diffraction-limited 12.8-μm Neii fine-structure emission line and 12.5-μm continuum images of the bright southern compact Hii region G333.6-0.2, taken with the mid-infrared imaging polarimeter NIMPOL. The two images show remarkably similar, compact, yet asymmetric, flux distributions. The [Neii] image shows a complex structure near the ionizing source(s) which we interpret in terms of the ionization structure of the Hii region. It is found that G333.6-0.2 is more likely to be excited by a cluster of O and B stars than by a single star.
