| 英文摘要 | We present Submillimeter Array (SMA) observations of the massive star-forming region IRAS 20126+4104 in the millimeter continuum and in several molecular line transitions. With the SMA data, we have detected nine molecular transitions, including deuterated hydrogen cyanide, CH(3)OH, H(2)CO, and HC(3)N molecules, and imaged each molecular line. From the 1.3 mm continuum emission a compact millimeter source is revealed, which is also associated with H(2)O, OH, and CH(3)OH masers. Using a rotation temperature diagram, we derive that the rotational temperature and the column density of CH(3)OH are 200 K and 3.7x10(17) cm(-2), respectively. The calculated results and analysis further indicate that a hot core coincides with IRAS 20126+4104. The position-velocity diagrams of H(2)CO (3(0,3)-2(0,2)) and HC(3)N (25-24) clearly present Keplerian rotation. Moreover, H(2)CO (3(0,3)-2(0,2)) is found to trace the disk rotation for the first time. |
