We present high angular resolution observations of the massive star-forming core DR21(OH) at 880 mu m using the Submillimeter Array (SMA). The dense core exhibits an overall velocity gradient in a Keplerian-like pattern, which breaks at the center of the core where SMA 6 and SMA 7 are located. The d...
