Resumen
Continuumdata at 25 and 88 GHz toward the luminous young stellar object IRAS 16547 4247 (G343.126 0.062)
have been obtained with the Australia Telescope Compact Array. The triple emission source identified previously at
lower frequencies has been detected at 25 GHz. For frequencies between 1.4 and 25 GHz, the flux density of the central
continuum source is well fitted with a power-law dependence that is consistent with thermal emission from a jet. The
two outer lobes are radio Herbig-Haro objects exhibiting thermal and nonthermal synchrotron emission. At 88 GHz,
one unresolved emission source was detected, centered on the radio jet. At this frequency the emission does not arise
from the jet but from the dusty molecular envelope within which the jet is embedded.
