Can the dust eclipses in WR 104 provide constraints on the system's inclination?
Noel D. Richardson, Ryan M. T. White, Anthony J. Fabrega +8
When two massive stars orbit each other, their winds create a shock cone. In some cases, an evolved, carbon-rich Wolf-Rayet (WR) star's wind collides with that of an orbiting OB st…
The formation and evolution of dust in the colliding-wind binary Apep revealed by JWST
Yinuo Han, Ryan M. T. White, Joseph R. Callingham +4
Carbon-rich Wolf-Rayet (WR) stars are significant contributors of carbonaceous dust to the galactic environment, however the mechanisms and conditions for formation and subsequent…
The Serpent Eating Its Own Tail: Dust Destruction in the Apep Colliding-Wind Nebula
Ryan M. T. White, Benjamin J. S. Pope, Peter G. Tuthill +5
Much of the carbonaceous dust observed in the early universe may originate from colliding wind binaries (CWBs) hosting hot, luminous Wolf-Rayet (WR) stars. Downstream of the shock…
Carbon-rich dust injected into the interstellar medium by Galactic WC binaries survives for hundreds of years
Noel D. Richardson, Micaela Henson, Emma P. Lieb +23
Some carbon-rich Wolf-Rayet stars (WC stars) show an infrared excess from dust emission. Dust forms in the collision of the WC wind with a companion star's wind. As this dust is ca…
Wolf-Rayet Colliding Wind Binaries
Ryan M. T. White, Peter Tuthill
Wolf-Rayet stars embody the final stable phase of the most massive stars immediately before their evolution is terminated in a supernova explosion. They are responsible for some of…
