Plasma Leakage from the Centrifugal Magnetospheres of Magnetic B-Type Stars

Magnetic B-type stars are often host to Centrifugal Magnetospheres (CMs). Here we describe the results of a population study encompassing the full sample of known magnetic early B-type stars, focusing on those with detectable CMs. We present revised rotational and magnetic parameters for some stars, clarifying their positions on the rotation-confinement diagram, and? find that plasma densities within their CMs are much lower than those predicted by centrifugal breakout.
