| Description | We present new numerical models of line-driven stellar winds of A supergiants. Statistical equilibrium (NLTE) equations of the most abundant elements are solved, and properly obtained occupation numbers are used to calculate consistent radiative force and radiative heating terms. Wind density, velocity, and temperature are calculated as a solution of model hydrodynamical equations. Our models allow for the calculation of wind mass-loss rate and terminal velocity. |
