Schematic view of an oblique rotator presenting a large-scale corotating structure (in grey) in the inner part of the wind of the WN star. θ and φ stand for the rotation and magnetic axes, respectively. In the upper configuration, the line of sight crosses the large-scale structure, therefore maximizing the absorption of the soft X-rays emitted at the base of the stellar wind. The lower configuration illustrates the relative position of the large-scale structure with respect to the line of sight half a rotational period later. In that case, we may expect a maximum in the soft X-ray lightcurve.
