Line Profile microvariability and wind structure for OB stars
Abstract
We report the results of a search for line profile variability (LPV) in the spectra of OB stars. The wavelets were used for looking for the irregular LPV in spectra of program stars. We connect the appearance of irregular details in the LPV with the formation and dissipation of the small-scale substructures (clumps) in the wind.
