5. Conclusions

We presented a multi-wavelength study of the region around the luminous IRAS source 12326-6245. Mid-infrared imaging revealed the presence of a deeply embedded proto-Trapezium system surrounded by a cluster of near-infrared sources. Two of the members of the Trapezium system are associated with UC H II regions detected by Walsh et al. (1998). The exciting stars of the two UC H II regions are of very similar spectral type (B0) if we assume that only one star dominates the energetics of each region and dust extinction in the ionized gas is of minor importance.

The molecular line maps led to the detection of one of the strongest molecular outflows in the southern sky. We obtain a mass loss rate of about [FORMULA] [FORMULA]/yr, a momentum rate of [FORMULA] [FORMULA]km s-1/yr and a mechanical luminosity of [FORMULA] [FORMULA].
