Abstract:	IRAS 04073 is a massive high mass star forming regions hosting massive protoclusters. Star formation in the vicinity of expanding HII region could toll different path from those of pristine environment. IRAS 04073+5102 (SH 209) provides an ideal region to study the influence of expanding region on the star formation activities in a region. We observed the region at 230 GHz with SMA and detected 12CO, 13CO, C18O and SO. We used SMA dust continuum and CO data to identify and characterize the major filaments and cores in the complex. The brightest mm clump of 4000 M☉ observed at low resolution fragments into just three cores and the prominent core is an excellent candidate for a massive protocluster. Comparing of SMA images with Spitzer images, we could isolate very young filaments containing pre-protoclusters that would likely form clusters. The expanding HII region may have contributed to the formation of the observed filamentary structures and in triggering star formation in the region.
