Infrared Study of the Southern Galactic Star Forming Region Associated with Iras 10049-5657

The southern Galactic star forming region associated with IRAS 10049-5657 has been mapped simultaneously in two far infrared bands (λ _eff = 150 & 210 μm), with ~ 1′ angular resolution using the TIFR 1-m balloon borne telescope. Spatial distribution of the temperature of cool dust and optical depth at 150 μm, have been obtained taking advantage of the similar beams in the two bands. The HIRES processed IRAS maps at 12, 25, 60 & 100 μm have been used for comparison. The distribution of warm dust emission as well as emission in the Unidentified Infrared Bands in the mid infrared have been studied, based on the MSX data (8, 12, 14, & 21 μm bands). Radiative transfer modelling has been carried out taking into account all available infrared measurements to obtain various physical parameters like nature of the exciting source, geometrical dimensions, dust distribution and composition etc.
