Solutions of a steady-state model with stellar parameters as in Table 2. (a) Temperature profile. (b) Velocity profile in solid line, the region of stagnation or negative acceleration in X markers. (c) Eddington ratios for full radiation force in solid line, only the OPAL contribution in dotted line, only CAK contribution in dashed line, and Γ = 1 in thin horizontal dashed line. (d) Profile of spherically modified optical depth. (e) Density Profile. Panels d,e: the vertical dotted line at R_ph = 4.48R_c = 4.48R_⊙ shows the location of the photosphere. The top axis gives the radial distance in units of R_⊙, but since in this paper R_c = R_⊙ this is also equivalent to normalising the radius to R_c.
