[C II] observation area (solid box) of RCW 36 superimposed on a composite image shown with the equatorial J2000 coordinate system: AKARI 9 μm (blue), Herschel 70 μm (green), and Herschel 250 μm (red). RCW 36 is formed in a large-scale filament extending north-south direction. A bipolar lobe, shell-like structures and a ring-like structure (black dashed ellipse) are identified by Minier et al. (2013).
