Measurements and Analysis of Helium-like Triplet Ratios in the X-Ray Spectra of O-Type Stars

We discuss new methods of measuring and interpreting the forbidden-to-intercombination line ratios of helium-like triplets in the X-ray spectra of O-type stars, including accounting for the spatial distribution of the X-ray-emitting plasma and using the detailed photospheric UV spectrum. Measurement...
