Abstract
High-resolution spectra of the J=17−16 CO line (1956 GHz) in the BN-KL region of Orion have been obtained with a heterodyne spectrometer. The profiles show a broad component with 30 km s⁻¹ (FWHM) linewidth and a narrower 8 km s⁻¹ component. The broader plateau emission detected over a range of transitions from J=1–0 to J=17−16 is analyzed under the assumptions of thermal equilibrium and optically thin wings to deduce an excitation temperature of 180 ± 50 K and minimum column density of 1 X 10¹⁸ cm⁻² for CO in this component.
