Descripción
We report TIMMI2 diffraction-limited mid-IR images of the multipolar PPN
IRAS 16594-4656. By using the Lucy-Richardson deconvolution algorithm we
recover a two-peaked morphology in the innermost region at 8.6 μm and
11.5 μm. We interpret the observed mid-IR structure as the detection
of the two limb-brightened peaks indicating the presence of a dusty
toroidal structure in IRAS 16594-4656. We find that the supposed
biconical openings of the dust torus are in good agreement with one of
the bipolar outflows identified in the HST optical images.
