Colliding Winds: Dust from Massive Galactic Wolf-Rayet Stars

Very massive hot stars distinguish themselves by their high luminosities and thus capacity to drive strong, fast winds. Binaries among massive stars are the norm rather than the exception. It is thus inevitable that the winds will collide in such systems, producing energetic phenomena that can be studied across the electromagnetic spectrum. In some cases, e.g. when the primary star has reached the enhanced-wind Wolf-Rayet (WR) phase as a carbon-rich WC star, copious quantities of carbon-based dust are produced and ejected into the ISM.
