Abstract
The formation of high mass stars is less well understood than that of lower mass stars due to the shorter time scales and larger distances involved. One of the earli­est stages of high mass star formation consists of a period of outflow which can be studied through its impact on its environment. We present observations of W28A2, a shell like Ultracompact HII region associated with one of the youngest and most energetic outflows in the Galaxy (05 star). Using the James Clerk Maxwell Tele­scope, we have observed the outflow in a number of transitions and have derived the age, mass, extent, and velocity of the outflow. In order to better constrain the driving mechanism of the outflow, we have conducted magneto-hydrodynamic simu­lations (using Zeus-MP and Jetget) of a high-velocity jet impacting on a surrounding molecular envelope.
