Variations in the spectra and pulse period of GX301-2

Creators

Description

Spectra from observations of GX301-2 (3U1223-62) by the Goddard x-ray spectroscopy experiment on OSO-8 show an absorption edge due to cool iron with column densities of a few x 1019/cm2. A decrease in intensity was associated with increased absorption and a spectrum similar to those of binary x-ray sources in absorption dips. Observed variations of the pulse period are consistent with Doppler shifts for reasonable orbit parameters
