The origin of X-ray emission lines associated with O- and B-type stars is the subject of continuing controversy. Leading theories point to shocks in the star's massive, radiation-driven winds as the source of the X-rays. In recent years Chandra has taken high-resolution X-ray spectra of several hot stars, revealing broad and often asymmetric line profiles. At the same time, theoretical calculations of line profiles from spherically-symmetric shock distributions in the wind have shown the potential to produce similar profile shapes. We have parameterized a spherically-symmetric, distributed-shock wind model and fit it to several lines from the O4f star ζ Puppis. Our fits suggest lower than expected X-ray continuum opacities, and onset of shock formation within a few stellar radii.
