Descripción
Mid-IR images at 8.7 9.7 and 12.5 µm are presented of the star
forming region GGD14 associated with the IRAS source 06084-0611. In an
area of ˜30arcsec around the IRAS position we have found two
mid-IR sources identified with the cometary compact HII region VLA1 and
with the faint and unresolved radio continuum source VLA4. The mid-IR
morphology of VLA1 is very similar to that of the radio continuum
suggesting a direct interaction between the ionized gas and dust. The IR
source associated with VLA4 shows a consistent IR excess and the derived
infrared luminosity L1-20=350 Lsun indicates the presence of a
young star later than B3 ionizing the hypercompact HII region. In
addition its spectrum between 2.47 and 11.62 µm observed by
ISOPHOT shows the presence of the infrared emission bands at 3.3 6.2
”7.7” 8.6 and 11.2 µm with relative intensity ratios
typical of compact HII regions. Finally the radio continuum source VLA2
present in the field and not detected in our mid-IR images shows an
infrared luminosity of ˜8.5Lsun confirming the nature of embedded
T-Tauri star
