Scientific paper

Wolf Rayets (WRs) are hot massive stars at a late stage of evolution. They are prominent signposts for high mass star formation and their massive winds have significant influence on the interstellar medium. A small but significant number of these stars in the Galaxy are known to produce copious amounts of dust. Given the hostile circumstellar environment, this raises interesting questions. Interferometric and aperture masking observations strongly indicate that binarity plays a pivotal role in the dust formation. I will briefly review high angular resolution observations in the near- and mid-infrared which shed some light on dusty WRs.
