Complex Organic Molecules in The S255IR Region: Maps and Spectra of Sources in the 210—250 GHz Range

We present the survey results of the S255IR star-forming region in the 210-250 GHz range observed with the SMA interferometric array. We have constructed 115 channel maps and integrated intensity maps in the emission lines of various molecules. Complex organic molecules are observed mainly in the direction of the hot core SMA1. Exceptions are methanol and methylacetylene, which are seen in the direction of the SMA2 core and bipolar outflows as well. Spectra in the direction of the SMA1 and SMA2 cores were obtained and 59 molecules were detected, including complex molecules of 8-10 atoms.
