New predictions for radiation-driven, steady-state mass-loss and wind-momentum from hot, massive stars. I. Method and first results

Understand

[Abridged] Context: Radiation-driven mass loss plays a key role in the life-cycles of massive stars.

• However, basic predictions of such mass loss still suffer from significant quantitative uncertainties.
• Aims: We develop new radiation-driven, steady-state wind models for massive stars with hot surfaces, suitable for quantitative predictions of global parameters like mass-loss and wind-momentum rates.
• Methods: The simulations presented here are based on a self-consistent, iterative grid-solution to the spherically symmetric, steady-state equation of motion, using full NLTE radiative transfer solutions in the co-moving frame to derive the radiative acceleration.
