Abstract

Mid-infrared images at 8.7, 9.7 and 12.5 $\mu \rm m$ are presented of the star forming region GGD 14 associated with the source IRAS 06084-0611. In an area of ~30″ around the IRAS position, two mid-infrared sources were found. One was identified with the cometary compact HII region VLA 1 and the second with the faint and unresolved radio continuum source VLA 4. The mid-infrared morphology of VLA 1 is very similar to that of the radio continuum suggesting a direct interaction between the ionized gas and the dust. The infrared source associated with VLA 4 shows a large infrared excess and its derived infrared luminosity is $L_{1-20~\mu \rm m} = 350~L_\odot$, indicating the presence of a young star later than B3. In addition, its spectrum between 2.47 and 11.62 $\mu \rm m$ observed by ISOPHOT shows the presence of infrared emission bands at 3.3, 6.2, 7.7, 8.6 and 11.2 $\mu \rm m$ with relative intensity ratios typical of compact HII regions. Finally, the radio continuum source VLA 2, undetected on our mid-infrared images, shows an infrared luminosity of ~$ 8.5~L_\odot$ confirming its nature of an embedded T-Tauri star.
