Comparison of the wind properties at 1 AU as predicted from Model A and Model B. Upper panel: wind mass loss rate as a function of stellar mass at several different rotation rates. We predict the wind mass loss rate using , which we derive from rotational evolution models in Paper II. Middle panels: wind speed at 1 AU as a function of mass for each rotation rate predicted by our two wind models. Lower panels: proton density at 1 AU as a function of mass for each rotation rate, calculated by combining the mass loss rate and wind speed predictions.
