The Rigidly Rotating Magnetosphere of σ Orionis E
The Rigidly Rotating Magnetosphere of σ Orionis E
We attempt to characterize the observed variability of the magnetic helium-strong star sigma Ori E in terms of a recently developed rigidly rotating magnetosphere model. This model predicts the accumulation of circumstellar plasma in two co-rotating clouds, situated in magnetohydrostatic equilibrium at the intersection between magnetic and rotational equators. We …
