A Highly-collimated Water Maser Bipolar Outflow in the Cepheus A HW3d Massive Protostellar Object
2012
Proceedings of the International Astronomical Union
AbstractWe report the results of multi-epoch very long baseline interferometry (VLBI) water (H2O) maser observations carried out with the VLBI Exploration of Radio Astrometry (VERA) toward the HW3d object within the Cepheus A star-forming region. We measured proper motions of 30 water maser features, tracing a compact bipolar outflow. This outflow is highly collimated, extending through ~400 mas (290 AU), and having a typical proper motion velocity of ~6 mas yr−1(~21 km s−1). The dynamical
