Wind inhomogeneities in low-Z environment : observations

We discuss the results of time-resolved spectroscopy of three presumably single Population I Wolf-Rayet stars in the Small Magellanic Cloud, where the ambient metallicity is $sim 1/5 Z_odot$. We were able to detect and follow numerous small-scale wind-embedded inhomogeneities in all observed stars....
