Anotace

V originále

We study the ultraviolet variability of evolved B[e], Be, and B stars from our Galaxy and from the Magellanic Clouds. We use IUE observations to derive fluxes of individual stars in the selected bands in the near-UV and far-UV regions. We diagnose the variability in the lines and the total flux variability. We discuss the origin of the UV light variability of studied stars. We detected pulsations in B[e] star HD 50138, LBV-type variations in HD 34664, and constant luminosity for a group of B[e] supergiants.
