Abstract

We present results of numerical simulations of wind variability in the magnetic B1 IVe star $\beta$ Cephei. 2D-MHD simulations are used to determine the structure of the wind. From these wind models we calculate line profiles for different aspect angles to simulate rotation. The results are compared with the observed UV wind line profiles.
