Ring nebulae around Wolf-Rayet stars in M33 as seen by SITELLE
Selin Tuquet, Nicole St. -Louis, Laurent Drissen +5
We have conducted an analysis of nebulae around Wolf-Rayet (WR) stars in M33 using data collected by the imaging Fourier transform spectrometer SITELLE at the Canada-France-Hawaii…
Polarimetric modeling of corotating interaction regions (CIRs) threading massive-star winds
R. Ignace, N. St-Louis, F. Proulx-Giraldeau
Massive star winds are complex radiation-hydrodynamic (sometimes magnetohydrodynamic) outflows that are propelled by their enormously strong luminosities. The winds are often found…
On the origin of variable structures in the winds of hot luminous stars
Yannick J. L. Michaux, Anthony F. G. Moffat, Andre-Nicolas Chene +1
Examination of the temporal variability properties of several strong optical recombination lines in a large sample of Galactic Wolf-Rayet (WR) stars reveals possible trends, especi…
Revealing the Asymmetry of the Wind of the Variable Wolf-Rayet Star WR1 (HD4004) Through Spectropolarization
Nicole St-Louis
In this paper, high quality spectropolarimetric observations of the Wolf-Rayet (WR) Star WR1 (HD4004) obtained with ESPaDOnS at CFHT are presented. All major emission lines present…
A Systematic Search for Corotating Interaction Regions in Apparently Single Galactic Wolf-Rayet Stars. II. A Global View of the Wind Variability
André-Nicolas Chené, Nicole St-Louis
This study is the second part of a survey searching for large-scale spectroscopic variability in apparently single Wolf-Rayet (WR) stars. In a previous paper (Paper I), we describe…
A Systematic Search for Corotating Interaction Regions in Apparently Single Galactic WR Stars. I. Characterizing the Variability
N. St-Louis, A. -N. Chene, O. Schnurr +1
We present the results of a systematic search for large-scale spectroscopic variability in apparently single Wolf-Rayet stars brighter than ~12.5. In this first paper we characteri…
New insights into the nature of the SMC WR/LBV binary HD 5980
C. Foellmi, G. Koenigsberger, L. Georgiev +14
We present the results of optical wavelength observations of the unusual SMC eclipsing binary system HD 5980 obtained in 1999 and 2004--2005. Radial velocity curves for the eruptin…
A near-IR [Fe II] line imaging survey of supernova remnants in M33
T. Morel, R. Doyon, N. St-Louis
We report on the first near-IR [Fe II] line imaging survey of extragalactic SNRs. Observations of a sample of 42 objects drawn from an optically-selected catalogue of SNRs in M33 p…
