Scientific paper

We propose to obtain phase-constrained HETG spectra of the candidate magnetic O star theta-1 Orionis C, the ionizing source of the Orion Nebula. theta-1 Ori C exhibits remarkable 15.4-day periodic X-ray, UV and optical line variations thought to arise from the interaction of a radiatively driven O-star wind with a magnetosphere. New MHD calculations predict that strong X-ray shocks and rotational modulation occur if the magnetic poles are inclined with respect to the rotation axis. HEG and MEG spectra obtained at X-ray min (phase 0.5) and max (phase 0.0) along with archival spectra obtained at phases 0.82 and 0.37 will be used to measure line ratios, line profiles and phase-dependent temperatures, abundances, and absorption to test magnetic wind shock emission models.
