Constraining properties of dust formed in Wolf-Rayet binary WR 112 using mid-infrared and millimeter observations
Donglin Wu, Yinuo Han, Peredur M. Williams +9
Binaries that host a carbon-rich Wolf-Rayet (WC) star and an OB-type companion can be copious dust producers. Yet the properties of dust, particularly the grain size distribution,…
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…
Dynamic Imprints of Colliding-wind Dust Formation from WR140
Emma P. Lieb, Ryan M. Lau, Jennifer L. Hoffman +24
Carbon-rich Wolf-Rayet binaries are a prominent source of carbonaceous dust that contribute to the dust budget of galaxies. The "textbook" example of an episodic dust producing WR…
