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
