Intrinsic polarization of Wolf-Rayet stars due to the rotational modulation of the stellar wind
Fast rotating Wolf-Rayet stars are expected to be progenitors of long duration. Spectral lines of Wolf-Rayet stars originate in expanding stellar wind, therefore. Intrinsic polarization of Wol...

The Quasi-WR Star HD 45166 Revisited
We studied the wind of the quasi Wolf-Rayet (qWR) star HD 45166. As a first step we modeled the observed UV spectra of this star by means of the state-of-the-art Potsdam Wolf-Rayet (PoWR) atmosphe...

Wolf-Rayet stars - what we know and what we don't
Today, we have a sufficiently complete picture of what the Wolf-Rayet (WR) stars are. Predictions of stellar evolution theory are in a good agreement, predictions of population synthesis also agree well with number of known...

Intrinsic polarization of Wolf-Rayet stars due to the rotational modulation of the stellar wind
Wolf-Rayet stars are regarded as candidates for progenitors of core-collapse with the previous studies of Wolf-Rayet stars. of stars are considered to be fast rotators. Their high rotatio...

Properties of massive stars in four clusters of the VVV survey
for a subset of them. In the Hertzsprung Russell diagram, the Wolf-Rayet stars are more evolved than WN stars. Mass loss rates among Wolf-Rayet stars are a factor of 10We present an anal...

Discovery of a New [WR] Star
Wolf-Rayet (WR) stars are evolved massive objects, famous for their spectra rich with emission lines. For the first time WR stars were described more than 150, the discovery of a new WR star, especially ba...

An extensive spectroscopic time series of three Wolf-Rayet stars - I. The lifetime of large-scale structures in the wind of WR 134
During the summer of 2013, a 4-month spectroscopic campaign took place to observe the variabilities in three Wolf-Rayet stars. The spectroscopic data have been analysed for WR 134 (WN6b), to better understand its behaviour ...

An extensive spectroscopic time series of three Wolf-Rayet stars - II. A search for wind asymmetries in the dust-forming WC7 binary WR137
We present the results of a 4-month, spectroscopic campaign of the Wolf-Rayet in the wind of the WC star. We find no evidence of large-scale periodic variations often intrinsic continuum polarization of this star. ...
