| Abstract | We present results of the analysis of the X‐ray spectrum of the giant O‐star δ Orionis (O9.5II), observed in the wavelength range 5–175 Å by the X‐ray detector HRC‐S in combination with the grating LETG on‐board Chandra. We report on the Temperatures, Emission measures, variability in the stellar wind, and the distance of the X‐ray emitting plasma to the stellar surface. |
