Spitzer mid-infrared study of compact HII regions in the Magellanic Clouds.

CHARMANDARIS V., HEYDARI-MALAYERI M. and CHATZOPOULOS E.

Abstract (from CDS):

We present a study of the mid-infrared properties and dust content of a sample of 27 HII ``blobs'', a rare class of compact HII regions in the Magellanic Clouds. A unique feature of this sample is that even though these HII regions are of high and low excitation they have nearly the same physical sizes ∼1.5-3pc. We base our analysis on archival 3-8µm infrared imagery obtained with the Infrared Array Camera (IRAC) on board the Spitzer Space Telescope. We find that despite their youth, sub-solar metallicity and varied degrees of excitation, the mid-infrared colors of these regions are similar to those of typical HII regions. Higher excitation ``blobs'' (HEBs) display stronger 8µm emission and redder colors than their low-excitation counterparts (LEBs).
