| Abstract: | The Wolf-Rayet stars represent an advanced stage of evolution of the most massive stars. Their next immediate stadium will
be supernova explosion. The most striking property of this very rare but exceptionally hot and bright objects is their extreme
mass loss, of the order of 10-5 solar mass per year. In turn of evolution before and during the Wolf-Rayet phase such stars eject a lot of matter (∼ 10 M⊙) with velocity up to 3000 km/s that surrounds the min the form of gas and dust. In the case of binary Wolf-Rayet star such
expanding envelope may interact with a companion (usually hot OB star) wind forming a tail extended for ∼ 100 AU. This spectacular
phenomenon as well as some other connected with Wolf-Rayet stars that can be studied with high spatial resolution instruments
(both astrometric and imaging) are reviewed.
