Scientific paper

We discuss the recent progress in modeling of X-ray irradiated atmospheres, where radiative transfer of both external radiation and self radiation of affected gas are computed. We present model atmospheres in both radiative and hydrostatic equilibrium, which include precise treatment of multiple Compton scattering process. Outgoing continuum spectra of our models demonstrate the effects of Compton redistribution of hard X-rays to lower energies. These spectra include also detailed profiles of fluorescent iron Kα lines, which are broadened and distorted by Compton scattering. Model spectra exhibit distinct Compton shoulders from the red side of the line with equivalent widths of the order of 50 eV.
