Aperture Synthesis Maps of NH2D and CH3OD Lines Toward Orion-KL: The Origin of NH3 and CH3OH
Published online by Cambridge University Press: 12 April 2016
Abstract
The 111−-101+ transition of NH2D and the 21−20 E transition of CH3OD were mapped toward Orion-KL with the Nobeyama Millimeter Array. The synthesized beamwidth is 4″ to 5″. NH2D and CH3OD are mainly distributed over the peak-intensity regions of NH3 and CH3OH in Orion A, respectively. These results suggest that “most” of the gas-phase ammonia and methanol in the region of Orion-KL originate from dust grains.
