Meier, D L

A general analytic theory of winds driven by super-Eddington luminosities is presented. The relevant parameters are the mass M of the central object, the radius r/sub i/ where luminosity and matter are injected, the ratio ..cap alpha..'' of the free-fall time to the heating time at r/sub i/, and the total luminosity L/sub L/ injected at r/sub i/. Several different regimes of dynamical wind structure are identified, and the analytic expressions are shown to agree with the numerical results of Paper I in the appropriate case. In its general form the theory is the optically thick (to electron scattering) counterpart to optically thin radiation pressure-driven stellar winds.
