Luminous Blue Variables (LBVs) are massive stars that are likely to be a transitionary phase between O stars and hydrogen-free classical Wolf–Rayet stars. The variability of these stars has been an area of study for both professional and amateur as

One objective of the Polstar spectropolarimetry mission is to characterize the degree of nonconservative mass transfer that occurs at various stages of binary evolution, from the initial mass reversal to the late Algol phase. The proposed instrument

The most massive stars are thought to lose a significant fraction of their mass in a steady wind during the main-sequence and blue supergiant phases. This in turn sets the stage for their further evolution and eventual supernova, and preconditions th

Θ Mus = HD 113904 is a massive multiple system containing the WC5/6 + O6/7V binary WR48 in a $19.1\, \mathrm{ d}$ circular orbit. Previous attempts to constrain the variable photometric properties of this binary subsystem have been thwarted by the d

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 spectrometer SITELLE at the Canada-France-Hawaii Telescope (CFHT). This a

We present the results of a four-month, spectroscopic campaign of the Wolf-Rayet dust-making binary, WR137. We detect only small-amplitude, random variability in the CIII5696 emission line and its integrated quantities (radial velocity, equivalent wi

Massive star binaries are critical laboratories for measuring masses and stellar wind mass-loss rates. A major challenge is inferring viewing inclination and extracting information about the colliding wind interaction (CWI) region. Polarimetric varia

WR22 = HD 92740 is a bright (V = 6.4 $mag$), intrinsically luminous, double-line WN7h + O9III-V binary exhibiting one sharp 8\% deep eclipse near periastron in its elliptical (e = 0.6) 80-day orbit, when the WR-star passes in front of the O star, wit

Background Sneddon syndrome is a rare, progressive small and medium-vessel vasculopathy characterized by the clinical occurrence of livedo racemosa and ischaemic cerebrovascular events. Objectives We present the clinical course and management of this
