Summary of magnetically channeled wind shock model applied to q1 Ori C
The X-ray emission lines of q1 Ori C
are quite narrow at all observed viewing angles -- as our MHD simulations predict.
And occultation of the magnetosphere by the star accounts nicely for the modest change in X-ray flux with viewing angle.
Finally, 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.
