VLTI-MIDI observations of the peculiar symbiotic system HD330036

摘要

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.
