Scientific paper

We present high angular resolution (˜0."3) VLA observations of the H2O (22.2 GHz) maser emission toward the .HH 80-81 thermal radio jet. We find that the H2O maser is located at ˜7" to the northeast of the core `of the jet, clearly not coincident with it. A deep 3.5 cm VLA radio continuum map reveals the presence of a weak ( ˜0.05±0.01 mJy) radio source coincident in position (within 0" 1) with the H2O maser. In this region, the thermal jet and the H2O maser are most probably being powered by different stars. We discuss this and other cases of thermal jets with nearby H2O maser emission.
