摘要: We present computed radiation spectra for the boundary layer (BL) of accretion disk that is formed near surface a neutron star. Both free-free processes and Comptonization were taken into account. Our computations are based on hydrodynamic solution obtained by Popham Sunyaev (2001) BL structure. The highly diluted compared to Planck same temperature. They complex in shape; particular, an intense Wien emission component their high-energy region at high rates. In general, harder than those observed actual X-ray sources. This result very temperature found BL. show such temperatures could from oversimplified treatment radiative transfer paper, which completely ignored frequency dependence matter opacity intensity. indicate moderate rates, proper with allowance leads appreciably lower plasma softer spectra.
