Some results for a wind model with Ṁ = 5 × 10^-6 M_⊙ yr^-1. a) Variation in the degree of condensation of Si into silicate dust with radial distance from the mass centre. b) Radial variation with distance of outflow velocity v (solid line), sonic velocity c_T (dashed line), and escape velocity from star (dotted line). c) Variation in p and T along the wind (solid line) and lines of constant nucleation rate (dashed lines). The crosses denote the pressure and temperature at the inner edge of the dust shell for the models of Table 1.
