| Description | We describe our own global (unified) hydrodynamic models of expanding atmospheres of hot stars. The models solve the hydrodynamic equations, kinetic equilibrium equations (non-LTE), and the comoving-frame radiative transfer equation consistently from the (nearly) hydrostatic photosphere to the supersonic wind. The model input parameters are the stellar effective temperature, radius, mass, and elemental abundances. For these stellar parameters, our code predicts the photosphere and wind structure and, in particular, the wind mass -loss rate and terminal velocity. The photospheric emergent flux and thermal structure nicely agree with the TLUSTY model atmospheres. |
