Radiative Processes, Spectral States and Variability of Black-Hole Binaries
Radiative Processes, Spectral States and Variability of Black-Hole Binaries
We review radiative processes responsible for X-ray emission in hard (low) and soft (high) spectral states of black-hole binaries. The main process in the hard state appears to be scattering of blackbody photons from a cold disk by thermal electrons in a hot inner flow, and any contribution from nonthermal …
