A colliding-wind model for the Wolf-Rayet system HD 152270.

LUEHRS S.

Abstract (from CDS):

New orbital elements for the binary system HD 152270 (WC7 + O6) are derived from high resolution observations and literature data, obtained between 1944 to 1989. Variations in position and structure of the peak profile, overlying the flat-topped C{3} 569.59 nm line, are used to derive a colliding wind model (cone model) for the system. The model is used to construct synthetic line profiles which are compared with the observed profiles.
