SMA Observations of the High Mass Protostellar Candidate IRAS 19411+2306 A

The detailed mechanisms that drive high mass star formation are still unknown. At early stages of evolution protostars undergo accretion, which is closely linked to mass outflow. Near the protostars the flows can be observed as ionized jets, which are connected to large scale molecular flows best observed in the CO rotational lines. To study the outflow process, we conducted Submillimeter Array (SMA) observations of the CO (J=2-1) transition (including isotopologues), and 1.3 mm continuum emission of the high mass star protostellar candidate IRAS 19411+2306 A. In this poster we present preliminary results of these observations in addition to previous 6 cm continuum data obtained with the VLA. We detect a 1.3 mm dust core coincident with the ionized jet as well as extended CO emission tracing a molecular flow. We discuss the relation of the CO flow to the ionized jet, and its implication for the evolutionary phase of the driving object.
