The galactic region G9.62+0.19 comprises several massive young stellar objects of different evolutionary stages. One of the most interesting objects (component F) is confirmed to be a molecular hot core. A feature which made this object unique among hot cores is the fact that it seemed to be associated with NIR emission. This contradicts with the high near-infrared optical depths usually observed towards hot cores and can only be understood if the distribution of the circumstellar matter deviates from spherical symmetry. Support for this view comes from our recent detection of a molecular outflow associated with source F. By utilizing high-resolution NIR data (obtained with the camera ISAAC at the VLT) as well as MIR data (observations using SpectroCam-10 at Mt. Palomar) we have explored the IR properties of this region and especially of the hot core. Our careful astrometry of the latter suggests that the beforementioned NIR emission is not a direct trace of the hot core. However, an indirect association between the molecular gas and the IR emission might not be ruled out completely. In combination with high-sensitive VLA radio maps and basic radiative transfer considerations we discuss the nature of individual objects as well as the global features of the region. Part of this work was supported by the German Deutsche Forschungsgemeinschaft (DFG).
