of magnetically channeled wind
shock model applied toq1Ori C
x-ray emission lines ofq1Ori C are quite narrow at all observed viewing angles -- as our MHD simulations predict.
occultation of the magnetosphere by the star accounts nicely for the modest change in x-ray flux with viewing angle.
He-like forbidden-to-intercombination line ratios in Mg and S indicate that the bulk of the X-ray emitting plasma is within 1 stellar radius of the photosphere - in accord with the MHD simulations.
