High Resolution $\lambda$=1mm CARMA Observations of Large Molecules in Orion-KL

Astrophysics 2009-11-13 v1

Abstract

We present high resolution, Combined Array for Research in Millimeter-Wave Astronomy (CARMA), λ\lambda=1mm observations of several molecular species toward Orion-KL. These are the highest spatial and spectral resolution 1mm observations of these molecules to date. Our observations show that ethyl cyanide [C2_2H5_5CN] and vinyl cyanide [C2_2H3_3CN] originate from multiple cores near the Orion hot core and IRc7. Additionally we show that dimethyl ether [(CH3_3)2_2O] and methyl formate [HCOOCH3_3] originate from IRc5 and IRc6 and that acetone [(CH3_3)2_2CO] originates only from areas where both N-bearing and O-bearing species are present.
