(Intrinsic) Variations of Wolf-Rayet Stars
Published online by Cambridge University Press: 03 August 2017
Abstract
Twenty - two Wolf-Rayet stars (12 of type WN and 10 of type UC) were observed in the years 1986-1990 with the VBLUW photometer of Walraven. Eight (WC and WN) objects appeared to be constant. Five of the in total 14 variable objects will be discussed in the present paper: UR46 (WN3 pec), WR50 (WC6+a), WR55 (WN8), WR86 (WC7) and WR123 (WN8).
Simultaneous spectroscopy is made for WR46 and WR50. These results will be also discussed in short.
