Abstract / Description:VV CrA VV CrA is one of the rare binary systems harbouring a so-called infrared companion (see contribution by Th. Ratzka & Ch. Leinert). While in 1987 this companion dominated at all infrared wavelengths, it is now fainter than the primary even in the N-band. This `fading' may provide the chance to reveal the underlying properties causing the existence of infrared companions. In the following we will present a preliminary interpretation of the interferometric observations obtained with MIDI that provide insights into the geometry of the dusty environment. They seem to favour a geometrical explanation for the different apppearances of the two components of VV CrA.
