Spectroscopic study of the long-period dust-producing WC7pd+O9 binary HD192641
L. Lefevre, S. V. Marchenko, S. Lepine +12
We present the results of an optical spectroscopic study of the massive Wolf-Rayet binary WR137. These data cover the dust-formation maximum in 1997. Combining all available measur…
Near-infrared identification of the counterpart to X1908+075: a new OB-supergiant X-ray binary
Thierry Morel, Yves Grosdidier
We report the near-infrared (IR) identification of the likely counterpart to X1908+075, a highly-absorbed Galactic X-ray source recently suspected to belong to the rare class of OB…
The bright optical afterglow of the long GRB 001007
J. M. Castro Cerón, A. J. Castro-Tirado, J. Gorosabel +35
We present optical follow up observations of the long GRB 001007 between 6.14 hours and ~468 days after the event. An unusually bright optical afterglow (OA) was seen to decline fo…
HST Imagery and CFHT Fabry-Perot 2-D Spectroscopy in Halpha of the Ejected Nebula M1-67: Turbulent Status
Yves Grosdidier, Anthony F. J. Moffat, Sébastien Blais-Ouellette +2
With HST-WFPC2 we have obtained a deep, H-alpha image of the WR nebula M1-67. With the interferometer of the Universite Laval (Quebec, Canada), we have obtained complementary Fabry…
