Abstract: | We have computed the dynamical evolution of homogeneous, spherical gaseous condensations in the atmosphere of a Wolf-Rayet star. The physical conditions in the condensations vary substantially in the course of their motion in the stellar wind, which should result in variations in the observed spectrum of the star. The condensations also move at velocities of up to 1000 km/s relative to the surrounding stellar wind. Variations of the physical conditions in these condensations should be taken into account in models of the stellar winds of Wolf-Rayet stars. |
