Abstract

In ADAFs most of the gravitational energy locally deposited in the disk by viscous processes is stored as internal energy of the ions. If the energy were transferred to the electrons rather than to the ions, it would be radiated efficiently, since electrons radiate much more efficiently than ions. In the accreting plasma, the temperature of the ions is thus much higher than that of the electrons (by some two orders of magnitude).
