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 shocksÉ
Éand 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
