Abstract :
Mid-infrared images at 8.7, 9.7 and 12.5 (mu)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 L1-20 (mu)m = 350 L(circled dot operator), indicating the presence of a young star later than B3. In addition, its spectrum between 2.47 and 11.62 (mu)m observed by ISOPHOT shows the presence of infrared emission bands at 3.3, 6.2, 7.7, 8.6 and 11.2 (mu)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(circled dot operator) confirming its nature of an embedded T-Tauri star.
