ud-Doula
and Owocki (2001) have performed MHD simulations of
magnetically channelled winds: Equatorward flow
inside closed field lines and associated strong shocks are seen.

The large x-ray luminosities
and hard x-ray spectra (of q1 Ori C and
t Sco) already argue against
instability-generated shocks…
…and suggest that a hybrid
wind-magnetic model might be appropriate, especially on q1 Ori C, on which an 1100 G dipole field
has been discovered
