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…
Constraints on Clumps in the Representative Wind of the WN8 Wolf-Rayet star HD96548 = WR40 with Simultaneous Broadband Light and Linear-Polarisation Variability
Richard Ignace, Anthony Moffat, Carmelle Robert +1
We report precision ground-based broadband optical intensity and linear-polarisation light-curves for the sky's brightest WN8 star, WR40. WN8 stars are notorious for their high lev…
New insights into the WR nebula M1-67 with SITELLE
Marcel Sévigny, Nicole St-Louis, Laurent Drissen +1
We present a detailed study of M1-67, a well-known nebula around the population I Wolf-Rayet star WR 124 (WNh 8), based on datacubes obtained with the imaging Fourier transform spe…
When does an old nova become a dwarf nova? Kinematics and age of the nova shell of the dwarf nova AT Cnc
Michael M. Shara, Laurent Drissen, Thomas Martin +1
The Z Cam-type dwarf nova AT Cnc displays a classical nova (CN) shell, demonstrating that mass transfer in cataclysmic binaries decreases substantially after a CN eruption. The hib…
The Vast Population of Wolf-Rayet and Red Supergiant Stars in M101: I. Motivation and First Results
Michael M. Shara, Joanne L. Bibby, David Zurek +3
M101 is an ideal target in which to test predictions of massive star birth and evolution. The large abundance gradient across M101 (a factor of 20) suggests that many more WR stars…
Searching for Wolf-Rayet Stars in M101
J. L. Bibby, P. A. Crowther, A. F. J. Moffat +3
Wolf-Rayet (WR) stars are the evolved descendants of massive O-type stars and are considered to be progenitor candidates for Type Ib/c core-collapse supernovae (SNe). Recent result…
