Abstract

We report on interferometry of the high-mass young stellar object M8E-IR performed with MIDI at the ESO-VLTI. The observations were carried out using the UT1-UT3 and UT2-UT3 baselines. The visibilities in the 8...13 micron range derived from the spectrally dispersed fringes indicate the presence of circumstellar emission presumably originating from warm dust. We resolve the MIR emission of M8E-IR and derive an extension between 15 and 30mas which correspond to linear sizes of 30-50AU at the distance of the source. These are the scales at which circumstellar disks around massive stars are expected. We discuss the properties of the dust envelope based on the results of our preliminary model and in the context of supplementary NACO observations.
