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…
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…
Search for Polycyclic Aromatic Hydrocarbons in the Outflows from Dust-Producing Wolf-Rayet Stars
S. V. Marchenko, A. F. J. Moffat
A combined mid-IR spectrum of five colliding-wind, massive, dust-producing Population I Wolf-Rayet (WR) binaries shows a wealth of absorption and emission details coming from the c…
A 10-hour period revealed in optical spectra of the highly variable WN8 Wolf-Rayet star WR 123
A. -N. Chené, C. Foellmi, S. V. Marchenko +6
Aims. What is the origin of the large-amplitude variability in Wolf-Rayet WN8 stars in general and WR123 in particular? A dedicated spectroscopic campaign targets the ten-hour peri…
New Constraints on the Origin of the Short-Term Cyclical Variability of the Wolf-Rayet Star WR 46
V. Hénault-Brunet, N. St-Louis, S. V. Marchenko +3
The Wolf-Rayet star WR 46 is known to exhibit a very complex variability pattern on relatively short time scales of a few hours. Periodic but intermittent radial velocity shifts of…
Population I Wolf-Rayet Runaway Stars: the Case of WR124 and its Expanding Nebula M1-67
S. V. Marchenko, A. F. J. Moffat, P. A. Crowther
In 1997 and 2008 we used the WFPC2 camera on board of the Hubble Space Telescope to obtain two sets of narrow-band H images of the runaway Wolf-Rayet (WR) star WR 124 surrounded…
