Astron. Astrophys. 325, 450-456 (1997) 6. ConclusionsWe have presented new observational evidence that the infrared
emission from the Circinus galaxy largely originates within a compact
region which increases with wavelength but is only a few pc across at
3.8µm, about 26pc around 10µm and still
Using a spherically symmetric radiative transfer code we have shown
that both the observed size versus wavelength and overall spectral
energy distribution are consistent with assuming that the infrared
emission is mostly from dust heated by the AGN. The many free
parameters in the model appear to be well constrained by the
observations. Although the starburst probably contributes to the
