Description
Low luminosity agns (LLAGNs) are posing a problem to the standard accretion AGN scenario because of their low radiation efficiency and the absence in their spectrum of the most significative feature of an accretion-disk: the blue bump. I will present results from high angular resolution observations in the IR of a set of prototype LLAGN which show that two other key features of AGN spectra, namelly, the red IR bump -signature of the torus - and the ~1 um inflection point, signature of the dust sublimation radius are also missing in these sources. But their centres are not devoided of material, a full reservoir de molecular material is available at their very centre.
