Conditions in the WR 140 wind-collision region revealed by the 1.083-micron He I line profile
Peredur M. Williams, Watson P. Varricatt, André-Nicolas Chené +10
We present spectroscopy of the P~Cygni profile of the 1.083-micron He I line in the WC7 + O5 colliding-wind binary (CWB) WR 140 (HD 193793), observed in 2008, before its periastron…
Revealing Efficient Dust-Formation at Low Metallicity in Extragalactic Carbon-Rich Wolf-Rayet Binaries
Ryan M. Lau, Matthew J. Hankins, Mansi M. Kasliwal +6
We present Spitzer/IRAC observations of dust formation from six extragalactic carbon-rich Wolf-Rayet (WC) binary candidates in low-metallicity (Z Z) environm…
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…
Revisiting the Impact of Dust Production from Carbon-Rich Wolf-Rayet Binaries
Ryan M. Lau, J. J. Eldridge, Matthew J. Hankins +3
We present a dust spectral energy distribution (SED) and binary stellar population analysis revisiting the dust production rates (DPRs) in the winds of carbon-rich Wolf-Rayet (WC)…
Variable dust emission by WC type Wolf-Rayet stars observed in the NEOWISE-R survey
Peredur M Williams
Photometry at 3.4 and 4.6 micron of 128 Population~I WC type Wolf-Rayet stars in the Galaxy and 12 in the Large Magellanic Cloud (LMC) observed in the WISE NEOWISE-R survey was sea…
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…
