标题： Model atmospheres of X-ray bursting neutron stars

摘要： 我们提出了低质量X射线双星中X射线爆发中子星的扩展模型大气和发射光谱集。康普顿散射被考虑在内。 这些模型是在LTE近似下为六种不同的化学成分计算的：纯氢和纯氦大气，以及具有太阳氢氦混合物和各种重元素丰度的大气：Z = 1, 0.3, 0.1, 和 0.01 Z_sun，在三种重力值 log g =14.0, 14.3, 和 14.6 下，以及在相对光度 l = L/L_Edd 范围 0.001 - 0.98 的 20 个值下。所有模型的发射光谱都用稀释的黑体光谱来拟合 RXTE/PCA 观测带 3 - 20 keV，并给出了相应的颜色校正因子 f_c 值。 我们还展示了如何使用这些依赖关系来估计中子星的基本参数。 显示英文摘要

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 and pure helium atmospheres, and atmospheres with a solar mix of hydrogen and helium and various heavy elements abundances: Z = 1, 0.3, 0.1, and 0.01 Z_sun, for three values of gravity, log g =14.0, 14.3, and 14.6 and for 20 values of relative luminosity l = L/L_Edd in the range 0.001 - 0.98. The emergent spectra of all models are fitted by diluted blackbody spectra in the observed RXTE/PCA band 3 - 20 keV and the corresponding values of color correction factors f_c are presented. We also show how to use these dependencies to estimate the neutron star's basic parameters.
