Abstract

Electron-positron pairs photoproduced in conventional unsaturated Compton disk and spherical accretion models with electron temperature greater than 10 to the 9 K are found to dominate over the background electrons. This results in an equilibrium temperature lower than previously found and severely constrains the model parameters in some cases. Electron-positron pair production does not alleviate the thermal instability of the optically thin two-temperature disk model.
