XB:1905+00 - a Very Compact Low-Mass Binary Viewed at Low Inclination
Abstract
Both the X-ray behavior and the intrinsic faintness of the optical counterpart of the burst source XB 1905+000 are suggestive of a very compact system viewed at low inclination. From the analysis of EXOSAT observations of the burst, in September 1985, a composite spectrum was revealed. Moreover, it was shown how the black body burst emission evolved into a small black body component seen in the persistent flux. Assuming an Eddington-limited peak, bolometric luminosity at a distance of about 8 kpc to the source was derived. Plausible constraints on the mass and radius of the neutron star were obtained.
