Recent advances in stellar magnetometry have revealed that approximately 10% of hot stars host stong, organized surface magnetic fields. Magnetic confinement of the ionized winds of massive, magnetic stars leads to the formation of magnetospheres which, due to their simple, stable fields, share many characteristics with the magnetospheres of giant planets. These magnetospheres can be probed by diagnostics across the electromagnetic spectrum, each of which is sensitive to a different magnetospheric region.
