Probing the gas kinematic and velocity gradients at milliarcsecond scale
The 6.7GHz methanol maser intimately associated with high-mass star-forming regions is a powerful tool to study the gas kinematics. We propose the second epoch EVN observation of two targets showing specific structures of the velocity gradient at mas scales. Our purpose is to examine a hypothesis that the observed velocity gradient of the maser emission is closely related to the gas kinematics. The velocity gradients of maser clouds will be used to identify accretion structures and to investigate launch mechanisms of outflows.
