Abstract:
We present high-resolution near-infrared and mid-infrared imaging,
mid-infrared spectroscopy and millimetre-wavelength continuum
observations of the nearby massive star-forming complex
IRAS 09002-4732. A rich cluster of young stars displaying
near-infrared excess emission is detected. We identify the ionising
source of the ultracompact H II region G268.42-0.85 and show that this
star is the dominant heating and illuminating source of the region.
Spectral type estimates based on different methods are consistent with
a star of spectral type O9. The combination of the new observations
with literature data allows us to set up the first structural model
for the region.
Description:
Table 5 contains coordinates and VLT/ISAAC photometry of the sources
detected in all three near-infrared bands in the field of
IRAS 09002-4732.
