Although there’s not good reason to think that these young O stars have convection or magnetic dynamos, they may have magnetic fields that remain from the the collapsing interstellar clouds
out of which they formed
In fact,q1Ori C itself has recently had a magnetic field detected on it: A large scale dipole filed
with a strength of 1100 G
(compare to 1 G for the Earth’s
They also have strong line-driven winds, so one might ask how does a wind behave in the presence of a large-scale magnetic field?
