Resumen:
A description is presented of the spectral features that characterize the spectrum of HD 190073 both in the photographic region (360-660 nm), and in the IUE UV (115-320 nm). A number of different types of profiles can be distinguished, and this seems to imply that many different ´broad´ regions of line formation coexist in the extended envelope of the star, including regions with densities differing in several orders of magnitude.
