Deuterated water in Orion-KL and W51M
Technical Report
·
OSTI ID:5299442
The author has mapped the HDO (l sub 10 - l sub 11) line emission in the Orion-KL region. Features with hot core, plateau, and 8 km/s ridge cloud characteristics are found. The HDO hot core and CH3CH2CN emissions are located between the infrared sources IRc2 and IRc4. In the Orion plateau source the abundance of H2O approaches that of CO. The possibility of an H2O enhancement in warm and dense regions is discussed. Reliable estimates of the (HDO)/(H2O)-ratio are not possible to give with the currently available observational data, since both species appear to be anomalously excited.
