Astrometric exoplanet detection survives solar-like stellar contamination
Conaire Deagan, Benjamin T. Montet, P. Tuthill +3
Astrometric monitoring of stars provides a promising method for discovery of low-mass planets around nearby Sun-like stars. The astronomical community has proposed several telescop…
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…
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…
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…
AU-scale radio imaging of the wind collision region in the brightest and most luminous non-thermal colliding wind binary Apep
B. Marcote, J. R. Callingham, M. De Becker +5
The recently discovered colliding-wind binary (CWB) Apep has been shown to emit luminously from radio to X-rays, with the emission driven by a binary composed of two Wolf-Rayet (WR…
The extreme colliding-wind system Apep: resolved imagery of the central binary and dust plume in the infrared
Y. Han, P. G. Tuthill, R. M. Lau +6
The recent discovery of a spectacular dust plume in the system 2XMM J160050.7-514245 (referred to as "Apep") suggested a physical origin in a colliding-wind binary by way of the "P…
Anisotropic winds in Wolf-Rayet binary identify potential gamma-ray burst progenitor
J. R. Callingham, P. G. Tuthill, B. J. S. Pope +5
The massive evolved Wolf-Rayet stars sometimes occur in colliding-wind binary systems in which dust plumes are formed as a result of the collision of stellar winds. These structure…
