X-ray spectra of Hercules X-1. II. The pulse
Journal Article
·
· Astrophys. J., Lett.; (United States)
The X-ray spectrum of Hercules X-1 was observed in the energy range 2--24 keV with sufficient temporal resolution to allow detailed study of spectral correlations with 1.24 s pulse phase. A well-defined segment of approx.1/10 the pulse light curve is found to exhibit a marked spectral evolution. Its edges are the sharpest temporal features in the pulse, with a duration of no more than 20 ms, and this portion of the light curve may be directly associated with the intrinsic underlying beam.
