Scientific paper

The authors have observed the bipolar flow source CRL 2591 in the NH3 (J,K) = (1,1) and (2,2) lines with the Effelsberg 100 m telescope. A compact ammonia cloud of ≡0.6 pc diameter around the central infrared source CRL 2591 was found and its mass was estimated to be ≡40 M_sun;. A velocity gradient in the direction orthogonal to the CO bipolar flow suggests that this compact ammonia cloud is rotating around the symmetry axis of the CO flow.
