Atomic physics of shocked plasma in the winds of massive stars

Maurice Leutenegger (NASA/GSFC/CRESST/UMBC),  David Cohen (Swarthmore College), Stan Owocki (Bartol Research Institute) High resolution diffraction grating spectra of x-ray emission from massive stars obtained with Chandra and XMM-Newton have revolutionized our understanding of their powerful, radiation-driven winds. Emission line shapes and line ratios … Continue reading
