TL;DR
This study investigates plasma leakage in the centrifugal magnetospheres of magnetic B-type stars, revealing lower plasma densities than predicted and refining stellar parameters to better understand their magnetic and rotational properties.
Contribution
It provides a comprehensive population analysis of magnetic B-type stars with CMs, updating stellar parameters and challenging existing models of plasma confinement.
Findings
Plasma densities in CMs are lower than centrifugal breakout predictions.
Revised stellar magnetic and rotational parameters clarify their positions in the rotation-confinement diagram.
The study enhances understanding of plasma leakage mechanisms in stellar magnetospheres.
Abstract
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.
