N2 - Hot stars emit most of their light in the ultraviolet. Therefore, the visual domain in which the variability is mostly studied traces just a small part of the spectral energy distribution. To overcome this, we searched archival data of the IUE satellite for the ultraviolet spectra of B[e] stars. We studied each star individually and identified the differences between the variability in the near and far ultraviolet domains. Although the data are typically very sparse, we detected the variability of the spectral energy distribution and of the line profiles. The variability has several sources of origin, including the light absorption by the dust clouds and the disk, pulsations, and eclipses in the case of binaries. The ultraviolet domain is the key to understanding the variability of B[e] stars.
