This is the luminous central dominating source located in the massive and dense molecular clump associated with IRAS 16562−3959. The HRLs exhibit Voigt profiles, which is a strong signature of Stark broadening. We successfully reproduce the observed continuum and HRLs simultaneously using a simple model of a slow ionized wind in local thermodynamic equilibrium, with no need for a high-velocity component. The Lorentzian line wings imply electron densities of 5 × 107 cm−3 on average. In addition, we detect SO and SO2 emission arising from a compact (∼3000 AU) molecular core associated with the central young star. The molecular core exhibits a velocity gradient that is perpendicular to the jet-axis, which we interpret as evidence of rotation. The set of observations toward G345.4938+01.4677 are consistent with it being a young high-mass star associated with a slow photo-ionized wind.en-USISM: jets and outflowsstars: jetsstars: formationISM: individual objects (IRAS 16562−3959)stars: individual (G345.4938+01.4677)Journal Article2017-02-2820142017-05-1810.1088/0004-637x/796/2/117
