The X-ray spectral properties of accretion discs in X-ray binaries. White, N. E., Stella, L., & Parmar, A. N. The Astrophysical Journal, 324:363–378, January, 1988.
Paper doi abstract bibtex Using EXOSAT observations, the spectral properties of the persistent emission from a number of X-ray burst sources, high-luminosity low-mass X-ray binaries, and galactic black hole candidates are compared with various models for X-ray emission from an accretion disk surrounding a compact object in a binary system. These models include the optically thick blackbody disk model considered by Mitsuda et al., two different disk models where the blackbody spectrum is modified by electron scattering, and a model where losses by the Comptonization of cool photons on hot electrons dominates the spectral formation. It is found that only a Comptonization model provides a good fit to all the spectra considered.
