Model for Cygnus X-3
It is shown that Cyg X-3 can be interpreted by means of the standard model'' for galactic x-ray sources in terms of mass loss from a large companion star and accretion on to a compact object. In the standard model'' assumed the x rays originate from a compact object and the infrared flux is due to heating of the companion star, or its extensive atmosphere or wind, by the x-ray star. A possible model for producing the x-ray light curve is outlined. It is suggested that the smooth variation of the x-ray luminosity is produced by a gradual and partial eclipse of the compact x-ray object by a stellar wind emanating from the larger companion. This same wind can also give rise to the mass transfer required to power the x-ray source, and it is assumed that the main opacity in the wind is electron scattering. (UK)
