K. ; Baliunas, S. L. ; Lester, J. B. Abstract Spectra of HD 153919 show a previously unreported broad emission line near 5293 A that is present at phases 0.2 and 0.8 and is absent or weaker at other phases, including the time of eclipse of the X-ray source. Approximate calculations suggest identification of this feature with the forbidden Fe XIV transition at 5303 A. This line may arise in the extended atmosphere of the primary ionized by the compact X-ray source or may occur in a high-temperature corona. Further monitoring is needed.
