Abstract
Atmospheric models and emitted X-ray spectra are calculated for X-ray bursting neutron stars taking into account the effects of Comptonization and free-free and bound-free emission/absorption. The color temperature obtained from the calculated X-ray spectra are significantly higher than the effective temperatures. The theoretical color temperature versus luminosity diagram is in good agreement with the observational diagram for MXB 1636-536 which was observed with Tenma. Based on such agreement, the distances to the burster and the Galactic center, and the mass and radius of the bursting neutron star are inferred.
