Phase-Dependent Line Profiles of VV CEP

Abstract

The normalized line profiles of VV Cep have been calculated by integrating the equation of transfer. The Sobolev theory was adopted and the wind velocity distribution was assumed to be V(r)=V∞(1-Rc/r)^(1/2). The peaks of the line profiles for the phase 0.06 and 0.80 appear at near half maximum and zero velocity of the wind, respectively.
