摘要：Using the EVN, we have observed water maser emission in the star forming region in L1287. It has been suggested that the maser emission is associated with an infalling-rotating disk around a young stellar object with the mass of 3 M¯. The distribution of maser radial velocities has persisted since previous VLA observations, supporting the above interpretation. Unfortunately, maser feature proper motions were not reliably traced because of the rapid temporal variation of maser feature locations between the observation epochs. We also found new maser features located in the SSW direction with respect to the known maser feature cluster, or in the same direction as that of the large-scale CO outflow. It also indirectly supports the existence of a disk/outflow system. However, it is also possible that all detected maser features are associated with an outflow with an extremely wide opening angle or an equatorial outflow.
