Abstract

This talk reviewed recent efforts to develop dynamical models for the effects of a surface dipole field on radiatively driven wind outflows. One particular project applies magnetohydrodynamic (MHD) simulations of a Magnetically Confined Wind ShockMCWS) model (originally developed by Babel & Montmerle 1997) to explain X-ray emission observed by Rosat (Gagné et al. 1997)from the magnetic O7V star θ1 Ori C.
