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 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…

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…

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…

A First Look with JWST Aperture Masking Interferometry (AMI): Resolving Circumstellar Dust around the Wolf-Rayet Binary WR 137 beyond the Rayleigh Limit

Ryan M. Lau, Matthew J. Hankins, Joel Sanchez-Bermudez +20

We present infrared aperture masking interferometry (AMI) observations of newly formed dust from the colliding winds of the massive binary system Wolf-Rayet (WR) 137 with JWST usin…

Deprojecting and constraining the vertical thickness of exoKuiper belts

James Terrill, Sebastian Marino, Richard A. Booth +3

Constraining the vertical and radial structure of debris discs is crucial to understanding their formation, evolution and dynamics. To measure both the radial and vertical structur…

From Dust to Nanodust: Resolving Circumstellar Dust from the Colliding-Wind Binary Wolf-Rayet (WR) 140

Ryan M. Lau, Jason Wang, Matthew J. Hankins +17

Wolf-Rayet (WR) 140 is the archetypal periodic dust-forming colliding-wind binary that hosts a carbon-rich WR (WC) star and an O-star companion with an orbital period of 7.93 years…

Has the dust clump in the debris disk of Beta Pictoris moved?

Yinuo Han, Mark C. Wyatt, William R. F. Dent

The edge-on debris disk of the nearby young star Beta Pictoris shows an unusual brightness asymmetry in the form of a clump. The clump has been detected in both the mid-IR and CO a…

Nested Dust Shells around the Wolf-Rayet Binary WR 140 observed with JWST

Ryan M. Lau, Matthew J. Hankins, Yinuo Han +29

Massive colliding-wind binaries that host a Wolf-Rayet (WR) star present a potentially important source of dust and chemical enrichment in the interstellar medium (ISM). However, t…

Resolving Decades of Periodic Spirals from the Wolf-Rayet Dust Factory WR 112

Ryan M. Lau, Matthew J. Hankins, Yinuo Han +9

WR 112 is a dust-forming carbon-rich Wolf-Rayet (WC) binary with a dusty circumstellar nebula that exhibits a complex asymmetric morphology, which traces the orbital motion and dus…
