摘要：We present an extended set of model atmospheres and emergent spectra of X-ray bursting neutron stars in low-mass X-ray binaries. Compton scattering is taken into account. The models were computed in LTE approximation for six different chemical compositions: pure hydrogen, pure helium, and solar mix of hydrogen and helium and various heavy elements abundances: Z = 1, 0.3, 0.1, and 0.01 Z⊙. For each chemical composition the models are computed for three values of gravity, logg =14.0, 14.3, and 14.6, and for 20 values of relative luminosity l = L/LEdd in the range 0.001–0.98. The emergent spectra of all models are fitted by the diluted blackbody in the redshifted RXTE/PCA band 3–20 keV and the corresponding values of color correction factors fc as function of l are presented. We also show how to use these dependencies to estimate the basic parameters of neutron stars.
