When a black hole accretes slowly, the radiative cooling of the infalling gas is weak and the accretion disk does not form. A hot, collisionless, quasi-spherical halo is formed instead. The properties of such halos are discussed. The rate of accretion, the radiative efficiency, and the temperature and density near the hole are evaluated.
