Scientific paper

A model for a stellar wind driven by acoustic waves in the linear regime is discussed, and the topology of the equation of momentum transport in the distance/velocity-plane is explored. For certain values of the wave dissipation length and the ratio of wave energy flux to thermal energy flux, three critical points are found, one of which is an attractor. Mass-loss rates for a star of 16 solar masses, a radius of 400 solar radii, and a temperature of 10,000 K are shown to range from 10 to the -28th to 0.0001 solar masses/yr.
