Large-scale Mapping Observations of DCN and DCO+ toward Orion KL
We present emission maps ( 1 .′ 5 × 1 .′ 5 scale, corresponding to 0.18 pc) of the DCN ( J = 2 − 1) and DCO + ( J = 2 − 1) lines in the 2 mm band toward the Orion KL region obtained with the 2 mm receiver system named B4R installed on the Large Millimeter Telescope. The DCN emission shows a peak at...

(

emission has been detected there. The DCO

emission shows enhancement at the west side of the hot core, which is well shielded from the UV radiation from OB massive stars in the Trapezium cluster. We have derived the abundance ratio of DCN/DCO

at three representative positions where both species have been detected. The gas components with

are associated with low abundance ratios of ∼4–6, whereas much higher abundance ratios (∼22–30) are derived for the gas components with

abundance ratios are explained by different densities. |
