Abstract:
We present a multiwavelength study of the ultra compact HII region
associated with IRAS 20178+4046. This enables us to probe the
different components associated with this massive star forming region.
Description:
The radio emission from the ionized gas was mapped at 610 and 1280MHz
using the Giant Metrewave Radio Telescope (GMRT), India. We have used
2MASS JHKs data to study the nature of the embedded sources associated
with IRAS 20178+4046. Submillimeter emission from the cold dust at 450
and 850um was studied using JCMT-SCUBA.
