Abstract

Massive stars (at least 8 times as massive as the Sun) possess strong stellar winds driven by radiation. With the advent of collaborations like MiMeS or BOB, an increasing number of these massive stars have been confirmed to have global magnetic fields. Such magnetic fields can have significant influence on the dynamics of these stellar winds, which are strongly ionized. Such interaction of the wind and magnetic field can generate copious amount of X-rays, can spin the star down, and can also help form large-scale disk-like structures. In this paper, we discuss the nature of such radiatively driven winds and how they interact with magnetic fields, often leading to confined winds.
