Abstract
Spectroscopy can be used as a tool to study stellar winds and mass-loss. The combination of spectroscopic data at several wavelengths, in particular Ultra-Violet (UV), visible and Infra-Red (IR), provides a complete picture of the stellar environment. In this paper, Be stars are taken as an example for which multiwavelength spectroscopy provides essential information on the stellar wind and mass-loss.
