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 Aromatic Infrared Bands around the Wolf-Rayet Binary WR140 Revealed by JWST

Kotomi Taniguchi, Ryan M. Lau, Takashi Onaka +12

We have analyzed the aromatic infrared bands (AIBs) in the 6-11.2 m range around the Wolf-Rayet binary WR140 (d=1.64 kpc) obtained with the James Webb Space Telescope (JWST) Mid…

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…

Visual Orbits of Wolf-Rayet Stars I: The Orbit of the dust-producing Wolf-Rayet binary WR\,137 measured with the CHARA Array

Noel D. Richardson, Gail H. Schaefer, Jan J. Eldridge +19

Classical Wolf-Rayet stars are the descendants of massive OB stars that have lost their hydrogen envelopes and are burning helium in their cores prior to exploding as type Ib/c sup…

The long-period spectroscopic orbit and dust creation in the Wolf-Rayet binary system WR 125

Noel D. Richardson, Andrea R. Daly, Peredur M. Williams +8

Several long-period binaries with a carbon-rich Wolf-Rayet star and an O star produce dust in their wind collisions. In eccentric binaries, this is seen most strongly near periastr…
