Abstract

We discuss here the results of the interferometric observations with MIDI at VLTI of the peculiar symbiotic system HD330036. The interferometric data resolve a complex dust nebula with possibly a bipolar shape or an elongated disk structure inclined at ∼ 70° to the line of sight and oriented with the polar axis at PA ∼ −5°. By fitting to the visibility data a radiative transfer model of the system we obtain a good fit assuming a distance of ∼ 500 pc, at the lower end of the range found in literature.
