Aspects of stellar wind theory as predicted by the full Navier-Stokes equations are considered, and an asymptotic analysis is carried out for a fixed viscosity parameter, in the cases of the thermal conduction parameter approaching 0 and approaching infinity. It is found to be possible to construct critical solutions for the wind velocity and temperature over the entire flow. All critical stellar wind solutions for given values of these parameters are categorized, and numerical solutions are obtained by integrating upstream from infinity, starting from initial values given by the Whang et al. (1966) expansions. Also discussed is the role of viscosity in stellar wind theory, and viscous and inviscid stellar wind solutions are compared.
