X-ray spectral diagnostics of activity in massive stars
David H. Cohen, Emma E. Wollman, Maurice A. Leutenegger
X-rays give direct evidence of instabilities, time-variable structure, and shock heating in the winds of O stars. The observed broad X-ray emission lines provide information about…

A mass-loss rate determination for zeta Puppis from the quantitative analysis of X-ray emission line profiles
David H. Cohen, Maurice A. Leutenegger, Emma E. Wollman +4
We fit every emission line in the high-resolution Chandra grating spectrum of zeta Pup with an empirical line profile model that accounts for the effects of Doppler broadening and…
