Scientific paper

We report the first far-IR detection of isotopic water in the Orion BN-IRc2 region from aboard the Kuiper Airborne Observatory. The observation of the 183.5290 mu m H218O 221 --> 212 emission line indicates that it is likely to originate from shocked gas in the outflow around Orion BN-IRc2, rather than from warm gas of the Orion plateau, where the H2O abundance is low ([H2O]/[H] <~ 2.5 x 10-5). Our observation infers a ratio of [H2O]/[H] <~ 1.7 x 10-3, which indicates that O is efficiently converted to H2O in shocked gas.
