Orbital phase variation of X-ray emission from Cyg X-3.

APPARAO K.M.V.

Abstract (from CDS):

The hard X-radiation (20-200keV) from Cyg X-3 shows a maximum at a phase 0.5 of the observed 4.8 hr modulation, while the soft X-radiation (2-12keV) shows a maximum at a phase 0.75.Both the emissions show a minimum at a phase 0.0. This behaviour can be explained by considering the X-ray emission both by the compact object and the hot post shock gas left by the passage of the compact object through the dense Wolf-Rayet primary; the attenuation and scattering by the electrons in the hot post shock gas, the Wolf-Rayet wind and the gas in the accretion wake is also used to construct the picture.
