Mid-infrared imaging of ultracompact H II regions

  • 16 Accesses


We discuss preliminary results of an 11.7 μm imaging survey of ultracompact H II regions from the Wood and Churchwell radio survey. We find that that the morphologies of ionized gas and warm dust are often significantly different, indicating that an H II region classification scheme should be based on more than radio data.
