Abstract:
Stars are formed in molecular clouds. Molecular outflow is an important dynamic feature of star formation and an important entry point for the study and understanding of star formation. Using the 13.7 m millimeter wave telescope of Delingha, Qinghai Observation Station of Purple Mountain Observatory, we used five molecular line probes (including
12CO,
13CO, C
18O, HCO+
J=1-0 and CS
J=2-1,
J is the quantum number of angular momentum). A massive star formation complex containing three sources IRAS 19230+1506, IRAS 19232+1504 and G050.3179--00.4186 were been mapped. Through the analysis of the above molecular spectral line data combined with infrared band sky survey data, we detected the molecular outflow activity for the first time in the three sources, and identified the central driver of the molecular outflow. Finally, the physical parameters related to the outflow is calculated for the three sources, and the relationship between these physical parameters is analyzed. The results show that the properties of the outflow is closely related to the properties of the central driving source.
