Near-infrared imaging observations of the southern massive star-forming region G333.6-0.2

Abstract

We present near-infrared broad-band JHK' images of the southern massive star-forming region G333.6−0.2. The slope of the K-luminosity function towards the region (0.24 ± 0.01) is considered to be equivalent to that expected for main-sequence stars in the solar neighbourhood. Point sources with their (H−K) colour greater than 1 are more likely to be located in extended emission and it is suggested that these objects are physically associated with the H ii region.
