摘要：

Characterizing the mass accretion phenomenon immediately surrounding the central young star remains particularly as an active research area for our understanding of the formation processes of massive stars. From the theoretical perspective, circumstellar discs around young stellar objects play a vital role in gauging the accretion as well as launching the jets and molecular outflows, through which angular momentum can be transported out and removed. Such disc-outflow interaction has been commonly observed in low mass protostellar systems. Do massive stars thus form like a scaled-up version of their low-mass counterpart? I will present our observational study on this subject with a case study toward the massive star forming core S255IR SMA1, a region which has been recently observed also with a luminosity burst.
