NEW TRENDS IN RADIO ASTRONOMY IN THE ALMA ERA: THE 30TH ANNIVERSARY OF NOBEYAMA RADIO OBSERVATORY 476 327-328 2013年 [査読有り]
We present the results of astrometry with VERA of the 22 GHz H2O maser burst in Orion KL started since 2011 February. According to the absolute positions and proper motions of the bursting H2O maser features, it is most likely that the outflow fro...
