Recent progress$^{1,2}$ in the application of numerical relaxation techniques has made possible the construction of steady-state boundary-layer solutions for thin alpha-disks around accreting unmagnetized stars. Physically acceptable solutions must satisfy the constraint that the radial inflow velocity not be supersonic. Preliminary results on new models of subsonic accretion will be presented.
