Intermediate-mass stars have weak stellar winds. Some have in addition strong magnetic fields that are able to channel wind streams and even to confine wind particles into a closed, dipolar magnetosphere rotating with the star. The shock from the confined wind generates x-rays and radio waves while the cooling wind downstream of the shock is turned into "clouds" that absorb the ultraviolet radiation from the star. In his Perspective, Montmerle reviews recent studies into the properties of these unusual "magnetic stars."
