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 q 1 Ori C
and t Sco) already argue against instability-generated shocksÉ
Éand suggest that a hybrid wind-magnetic model might be
appropriate, especially on q 1 Ori C, on which an 1100 G dipole
field has been discovered
