Shock-heated NH3 in a Molecular Jet Associated with a High-Mass Young Star
{{output}}
We present the discovery of shock-excited NH3 in a well-collimated jet associated with the extremely young high-mass star IRAS 20126+4104. The NH3 (3, 3) and (4, 4) emission is dominated by three clumps along the SiO jet. At the end of the jet, there exists st... ...
